Deuteronomy 1:40

38Joshua the son of Nun, who stands before you, shall go in there. Encourage him, for he shall cause Israel to inherit it.

39Moreover your little ones, whom you said would be captured or killed, your children, who today have no knowledge of good or evil, shall go in there. I will give it to them, and they shall possess it.

40But as for you, turn, and take your journey into the wilderness by the way to the Red Sea.”

41Then you answered and said to me, “We have sinned against the LORD. We will go up and fight, according to all that the LORD our God commanded us.” Every man of you put on his weapons of war, and presumed to go up into the hill country.

42The LORD said to me, “Tell them, ‘Don’t go up and don’t fight; for I am not among you, lest you be struck before your enemies.’”
