12Take care, brothers and sisters, that none of you may have an evil, unbelieving heart that turns away from the living God. 13But exhort one another every day, as long as it is called “today,” so that none of you may be hardened by the deceitfulness of sin. 14For we have become partners of Christ, if only we hold our first confidence firm to the end. 15As it is said,
“Today, if you hear his voice, do not harden your hearts as in the rebellion.”
16Now who were they who heard and yet were rebellious? Was it not all those who left Egypt under the leadership of Moses? 17But with whom was he angry forty years? Was it not those who sinned, whose bodies fell in the wilderness? 18And to whom did he swear that they would not enter his rest, if not to those who were disobedient? 19So we see that they were unable to enter because of unbelief.
