Numbers 14:39-45 - Israel Defeated In Battle
39 And when Moses put these words before the children of Israel, the people were full of grief. 40 And early in the morning they got up and went to the top of the mountain, saying, We are here and we will go up to the place which the Lord said he would give us: for we have done wrong.
41 And Moses said, Why are you now acting against the Lord's order, seeing that no good will come of it? 42 Go not up, for the Lord is not with you, and you will be overcome by those who are fighting against you. 43 For the Amalekites and the Canaanites are there before you, and you will be put to death by their swords: because you have gone back from the way of the Lord, the Lord will not be with you.
44 But they gave no attention to his words and went to the top of the mountain, though Moses and the ark of the Lord's agreement did not go out of the tent-circle. 45 Then the Amalekites came down, and the Canaanites who were living in the hill-country, and overcame them completely, driving them back as far as Hormah.
