Deuteronomy 1:43

So I spake unto you,.... The words, the orders he had received from the Lord to deliver to them:

and ye would not hear; so as to obey them, and act according to them:

but rebelled against the commandment of the Lord: as before, by not going up when he would have had them gone, and now by attempting it when he forbid them:

and went presumptuously up into the hill; that is, of themselves, in their own strength, disregarding the commandment of God, and what they were threatened with; this they endeavoured to do, for they were not able to effect it; the Amorites, perceiving them to make up the hill, came pouring down upon them in great numbers, and stopped them, and obliged them to retreat; see Numbers 14:45.
