I was forty years old when Moses the servant of the LORD sent me from Kadesh-barnea to spy out the land; and I brought him an honest report. 8But my companions who went up with me made the heart of the people melt; yet I wholeheartedly followed the LORD my God. And Moses swore on that day, saying, 'Surely the land on which your foot has trodden shall be an inheritance for you and your children forever, because you have wholeheartedly followed the LORD my God.' And now, as you see, the LORD has kept me alive, as he said, these forty-five years since the time that the LORD spoke this word to Moses, while Israel was journeying through the wilderness; and here I am today, eighty-five years old. I am still as strong today as I was on the day that Moses sent me; my strength now is as my strength was then, for war, and for going and coming. (NRSV 14:7-11)
Forty years old was I when Moses the servant of the LORD sent me from Kadeshbarnea to espy out the land; and I brought him word again as it was in mine heart. Nevertheless my brethren that went up with me made the heart of the people melt: but I wholly followed the LORD my God. And Moses sware on that day, saying, Surely the land whereon thy feet have trodden shall be thine inheritance, and thy children's for ever, because thou hast wholly followed the LORD my God. And now, behold, the LORD hath kept me alive, as he said, these forty and five years, even since the LORD spake this word unto Moses, while the children of Israel wandered in the wilderness: and now, lo, I am this day fourscore and five years old. As yet I am as strong this day as I was in the day that Moses sent me: as my strength was then, even so is my strength now, for war, both to go out, and to come in. (KJV 14:7-11)
Joshua tells the Israelites of a time he showed courage in the face of adversity, explaining he's just as brave now as he was when he first entered into the Promised Land. Does it sound like Joshua is full of himself? Or maybe he's trying to convince himself? You decide.
