Hebrews 10:39

³⁷ For yet a little while, and he that shall come will come, and will not tarry.

³⁸ Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.

But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.

Do read the surrounding verses too, because the context often says more than a single verse.
