Hebrews 12:14-17

¹⁴ Pursue peace with all men, and the sanctification without which no one will see the Lord. ¹⁵ See to it that no one comes short of the grace of God; that no root of bitterness springing up causes trouble, and by it many be defiled; ¹⁶ that there be no immoral or godless person like Esau, who sold his own birthright for a single meal. ¹⁷ For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears.
