Loyalty is what God demands from Judah and Israel. They shouldn't get distracted by other gods, or by lust for cash or craving for power. It's closely tied in with obedience, but there's an element of fervor and love tying it all up. At the same time, God's loyalty to his people is also important. God keeps promising that he will, in the end, own up to all his promises. He will guide everyone to a state of peace—even if they kick and scream along the way. People are going to get rewarded for remaining loyal to him. So, you know, it's a two way street.
