Deuteronomy 1:41-45

41"Then you answered me, 'We have sinned against the Lord. We ourselves will go up and fight, just as the Lord our God commanded us.' And every one of you fastened on his weapons of war and thought it easy to go up into the hill country.

42And the Lord said to me, 'Say to them, Do not go up or fight, for I am not in your midst, lest you be defeated before your enemies.'

43So I spoke to you, and you would not listen; but you rebelled against the command of the Lord and presumptuously 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 beat you down in Seir as far as Hormah.

45And you returned and wept before the Lord, but the Lord did not listen to your voice or give ear to you.
