He said, "What then may be done for her?" Gehazi answered, "Well, she has no son, and her husband is old." He said, "Call her." When he had called her, she stood at the door. He said, "At this season, in due time, you shall embrace a son." She replied, "No, my lord, O man of God; do not deceive your servant." The woman conceived and bore a son at that season, in due time, as Elisha had declared to her. (NRSV 4:14-17)
And he said, What then is to be done for her? And Gehazi answered, Verily she hath no child, and her husband is old. And he said, Call her. And when he had called her, she stood in the door. And he said, About this season, according to the time of life, thou shalt embrace a son. And she said, Nay, my lord, thou man of God, do not lie unto thine handmaid. And the woman conceived, and bare a son at that season that Elisha had said unto her, according to the time of life. (KJV 4:14-17)
This is how real loyalty is rewarded. In a way, it's a recapitulation of what happens with Abraham's wife, Sarah, in Genesis when she bears a child while apparently barren and in old age. The prophet's miracles sometimes have this kind of historical resonance, alluding to an earlier event.
But he said, "As the Lord lives, whom I serve, I will accept nothing! " He urged him to accept, but he refused. Then Naaman said, "If not, please let two mule-loads of earth be given to your servant; for your servant will no longer offer burnt offering or sacrifice to any god except the Lord. But may the Lord pardon your servant on one count: when my master goes into the house of Rimmon to worship there, leaning on my arm, and I bow down in the house of Rimmon, when I do bow down in the house of Rimmon, may the Lord pardon your servant on this one count." (NRSV 5:16-18)
But he said, As the Lord liveth, before whom I stand, I will receive none. And he urged him to take it; but he refused. And Naaman said, Shall there not then, I pray thee, be given to thy servant two mules' burden of earth? for thy servant will henceforth offer neither burnt offering nor sacrifice unto other gods, but unto the Lord. In this thing the Lord pardon thy servant, that when my master goeth into the house of Rimmon to worship there, and he leaneth on my hand, and I bow myself in the house of Rimmon: when I bow down myself in the house of Rimmon, the Lord pardon thy servant in this thing. (KJV 5:16-18)
God understands the complicated situations humans are involved in. Hence he doesn't have a problem with Naaman bowing down to a foreign god for political reasons, as long as his heart is wholly devoted to the one God.
"You shall strike down the house of your master Ahab, so that I may avenge on Jezebel the blood of my servants the prophets, and the blood of all the servants of the Lord. For the whole house of Ahab shall perish; I will cut off from Ahab every male, bond or free, in Israel. I will make the house of Ahab like the house of Jeroboam son of Nebat, and like the house of Baasha son of Ahijah. The dogs shall eat Jezebel in the territory of Jezreel, and no one shall bury her." Then he opened the door and fled. (NRSV 9:7-10)
And thou shalt smite the house of Ahab thy master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of the Lord, at the hand of Jezebel. For the whole house of Ahab shall perish: and I will cut off from Ahab him that pisseth against the wall, and him that is shut up and left in Israel: And I will make the house of Ahab like the house of Jeroboam the son of Nebat, and like the house of Baasha the son of Ahijah: And the dogs shall eat Jezebel in the portion of Jezreel, and there shall be none to bury her. And he opened the door, and fled. (KJV 9:7-10)
Jehu is commissioned with preserving his loyalty to God, but the consequences of doing that are to rebel against Ahab's house and Jezebel, killing them for their disloyalty.
He commanded them, "This is what you are to do: one-third of you, those who go off duty on the sabbath and guard the king's house (another third being at the gate Sur and a third at the gate behind the guards), shall guard the palace; and your two divisions that come on duty in force on the sabbath and guard the house of the Lord." (NRSV 11:5-7)
And he commanded them, saying, This is the thing that ye shall do; A third part of you that enter in on the sabbath shall even be keepers of the watch of the king's house; and a third part shall be at the gate of Sur; and a third part at the gate behind the guard: so shall ye keep the watch of the house, that it be not broken down. And two parts of all you that go forth on the sabbath, even they shall keep the watch of the house of the Lord about the king. (KJV 11:5-7)
So, these soldiers are being really loyal to baby Joash. Yeah… What else is there to say? It's also sort of treason against Athaliah, though she's so treasonous herself, and the soldiers are being loyal to the rightful heir.
Now when Elisha had fallen sick with the illness of which he was to die, King Joash of Israel went down to him, and wept before him, crying, "My father, my father! The chariots of Israel and its horsemen! " Elisha said to him, "Take a bow and arrows"; so he took a bow and arrows. Then he said to the king of Israel, "Draw the bow"; and he drew it. Elisha laid his hands on the king's hands. Then he said, "Open the window eastward"; and he opened it. Elisha said, "Shoot"; and he shot. Then he said, "The Lord's arrow of victory, the arrow of victory over Aram! For you shall fight the Arameans in Aphek until you have made an end of them. " He continued, "Take the arrows"; and he took them. He said to the king of Israel, "Strike the ground with them"; he struck three times, and stopped. Then the man of God was angry with him, and said, "You should have struck five or six times; then you would have struck down Aram until you had made an end of it, but now you will strike down Aram only three times." (NRSV 13:14-19)
Now Elisha was fallen sick of his sickness whereof he died. And Joash the king of Israel came down unto him, and wept over his face, and said, O my father, my father, the chariot of Israel, and the horsemen thereof. And Elisha said unto him, Take bow and arrows. And he took unto him bow and arrows. And he said to the king of Israel, Put thine hand upon the bow. And he put his hand upon it: and Elisha put his hands upon the king's hands. And he said, Open the window eastward. And he opened it. Then Elisha said, Shoot. And he shot. And he said, The arrow of the Lord's deliverance, and the arrow of deliverance from Syria: for thou shalt smite the Syrians in Aphek, till thou have consumed them. And he said, Take the arrows. And he took them. And he said unto the king of Israel, Smite upon the ground. And he smote thrice, and stayed. And the man of God was wroth with him, and said, Thou shouldest have smitten five or six times; then hadst thou smitten Syria till thou hadst consumed it: whereas now thou shalt smite Syria but thrice. (KJV 13:14-19)
Even though Joash of Israel isn't technically a "good" king, he's apparently not bad enough to earn the disrespect of prophets. The loyalty of God towards his people transcends Joash's flaws, leading to this guarantee of a qualified victory over Aram.
King Shalmaneser of Assyria came up against him; Hoshea became his vassal, and paid him tribute. But the king of Assyria found treachery in Hoshea; for he had sent messengers to King So of Egypt, and offered no tribute to the king of Assyria, as he had done year by year; therefore the king of Assyria confined him and imprisoned him. (NRSV 17:3-4)
Against him came up Shalmaneser king of Assyria; and Hoshea became his servant, and gave him presents. And the king of Assyria found conspiracy in Hoshea: for he had sent messengers to So king of Egypt, and brought no present to the king of Assyria, as he had done year by year: therefore the king of Assyria shut him up, and bound him in prison. (KJV 17:3-4)
Hoshea is disloyal to the king of Assyria—but in a sense, maybe this is because he's trying to remain loyal to his own people, to Israel.
Isaiah said, "This is the sign to you from the Lord, that the Lord will do the thing that he has promised: the shadow has now advanced ten intervals; shall it retreat ten intervals?" Hezekiah answered, "It is normal for the shadow to lengthen ten intervals; rather let the shadow retreat ten intervals." The prophet Isaiah cried to the Lord; and he brought the shadow back the ten intervals, by which the sun had declined on the dial of Ahaz. (NRSV 20:9-11)
And Isaiah said, This sign shalt thou have of the Lord, that the Lord will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees? And Hezekiah answered, It is a light thing for the shadow to go down ten degrees: nay, but let the shadow return backward ten degrees. And Isaiah the prophet cried unto the Lord: and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz. (KJV 20:9-11)
Rather than having a human demonstrate his loyalty to God, this is a moment where God demonstrates his loyalty to a human. He rewards Hezekiah by adding fifteen years onto his life, sealing the deal with this miracle.
The king commanded all the people, "Keep the passover to the Lord your God as prescribed in this book of the covenant." No such passover had been kept since the days of the judges who judged Israel, even during all the days of the kings of Israel and of the kings of Judah; but in the eighteenth year of King Josiah this passover was kept to the Lord in Jerusalem. (NRSV 23:21-23)
And the king commanded all the people, saying, Keep the passover unto the Lord your God, as it is written in the book of this covenant. Surely there was not holden such a passover from the days of the judges that judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah; but in the eighteenth year of king Josiah, wherein this passover was holden to the Lord in Jerusalem. (KJV 23:21-23)
Josiah demonstrates himself to be a particularly loyal king. He makes sure that Judah sticks with God (and with their traditions) in a way not even David had managed, celebrating the first Passover in ages.
