Hebrews 4:1-9

ASV(i) 1 Let us fear therefore, lest haply, a promise being left of entering into his rest, any one of you should seem to have come short of it. 2 For indeed we have had good tidings preached unto us, even as also they: but the word of hearing did not profit them, because it was not united by faith with them that heard. 3 For we who have believed do enter into that rest; even as he hath said,
As I sware in my wrath,
They shall not enter into my rest
:
although the works were finished from the foundation of the world. 4 For he hath said somewhere of the seventh [day] on this wise, And God rested on the seventh day from all his works; 5 and in this [place] again, They shall not enter into my rest. 6 Seeing therefore it remaineth that some should enter thereinto, and they to whom the good tidings were before preached failed to enter in because of disobedience, 7 he again defineth a certain day, To-day, saying in David so long a time afterward (even as hath been said before),
Today if ye shall hear his voice,
Harden not your hearts.
8 For if Joshua had given them rest, he would not have spoken afterward of another day. 9 There remaineth therefore a sabbath rest for the people of God.
