Hebrews 4:1; Hebrews 4:6-8
Let us therefore fear , lest, a promise being left us of entering into his rest, any of you should seem to come short of it .
Seeing therefore it remaineth that some must enter therein , and they to whom it was first preached entered not in because of unbelief:
Again, 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.
For if Jesus had given them rest , then would he not afterward have spoken of another day.
