Hebrews 12:15-17

Young's Literal Translation

¹⁵ looking diligently over lest any one be failing of the grace of God, lest any root of bitterness springing up may give trouble, and through this many may be defiled;

¹⁶ lest any one be a fornicator, or a profane person, as Esau, who in exchange for one morsel of food did sell his birthright,

¹⁷ for ye know that also afterwards, wishing to inherit the blessing, he was disapproved of, for a place of reformation he found not, though with tears having sought it.
