Hebrews 3:12-19

12See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. 13But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. 14We have come to share in Christ, if indeed we hold our original conviction firmly to the very end. 15As has just been said: “Today, if you hear his voice, do not harden your hearts as you did in the rebellion.” 16Who were they who heard and rebelled? Were they not all those Moses led out of Egypt? 17And with whom was he angry for forty years? Was it not with those who sinned, whose bodies perished in the wilderness? 18And to whom did God swear that they would never enter his rest if not to those who disobeyed? 19So we see that they were not able to enter, because of their unbelief.
