“Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief:”
Hebrews 4:6 (KJV)
Context Reading
4For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. 5And in this place again, If they shall enter into my rest. 6Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief: 7Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts. 8For if Jesus had given them rest, then would he not afterward have spoken of another day.
