Hebrews 3:13-15

RKJNT(i) 13 But encourage one another daily, while it is called Today; lest any of you be hardened by the deceitfulness of sin. 14 For we have become partakers of Christ, if we hold our first confidence steadfast to the end; 15 While it is said, Today if you will hear his voice, do not harden your hearts, as in the rebellion.
