Hebrews 3:16-19

For who were they who heard and yet provoked Him [with rebellious acts]? Was it not all those who came out of Egypt led by Moses? And with whom was He angry for forty years? Was it not with those who sinned, whose dead bodies were scattered in the desert? And to whom did He swear [an oath] that they would not enter His rest, but to those who disobeyed [those who would not listen to His word]? So we see that they were not able to enter [into His rest—the promised land] because of unbelief and an unwillingness to trust in God. [Num 14:1-35]
