Hebrews 12:16

Heb. 12:16. Lest there (be) any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.

In the "Folly of Procrastination" Hebrews 12:16 shows the danger of counting on a death-bed repentance:

Is it not the very ground on which you venture so and so to gratify your lusts? Let young people examine all their secret carriage; what they do alone in the dark and in secret corners. God knoweth, and your own hearts know, though men do not know. Put the question impartially to your own consciences; is not this the very thing that gives you the courage to do as you do, that you hear that God is a very merciful God, and that he often of his sovereign mercy gives repentance of great sins, and even willful sins, and in consequence of repentance forgives? And so you hope that one day or other he will do so to you. You intend some time hereafter earnestly to seek it; and you hope you shall be awakened. And if you be very earnest, as you intend to be, you hope you shall be converted, and then you shall be forgiven, and it will be as well as if you had never committed such sins.

If this be the case consider how you boast of to-morrow, and foolishly depend on future opportunity to repent, as well as foolishly presume on the mercy of God to give you repentance, at the same time that you take a course to provoke God, forever to give you up to a sealed hardness and blindness, and to a most fearful damnation; not considering that God will glorify his revenging justice as well as his mercy; nor remembering the sad example of Esau, "who for a morsel of meat sold his birthright; and afterwards, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears." Hebrews 12:16-17.
