Therefore we ought to give the more earnest heed to the things which we have heard, lest haply we let them slip.

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

Let us then fear, since a promise is still left us of entering into his rest, lest any one of you should appear to fail of obtaining it.

And beyond all contradiction the less is blessed by the greater.

For consider him that endured such contradiction by sinners against him, lest ye faint in your souls, and become weary.

looking diligently, lest any one come short of the grace of God; lest any root of bitterness springing up trouble you, and the many be thereby defiled;

lest there be any fornicator, or profane person as Esau, who for one meal sold even his birthright.
