Hebrews 2:1; Hebrews 3:12; Hebrews 4:1; Hebrews 9:17

1 Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.

12 Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

1 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.

17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
