Deuteronomy 1:41-45

41“Then you answered and said to me, ‘We have sinned against the Lord. We will go up and fight, just as the Lord our God has commanded us.’ So you equipped every man with weapons of war, and regarded it as easy to go up into the hill country.

42But the Lord said to me, ‘Say to them, “Do not go up and do not fight, for I am not among you [because of your rebellion]; otherwise you will be [badly] defeated by your enemies.” ’

43So I spoke to you, but you would not listen. Instead you rebelled against the command of the Lord, and acted presumptuously and went up into the hill country.

44Then the Amorites who lived in that hill country came out against you and chased you as bees do, and struck you down in Seir as far as Hormah.

45And you returned and wept before the Lord; but the Lord would not listen to your voice nor pay attention to you.
