Hebrews 12:14 KJV

Wherefore lift up the hands which hang down, and the feeble knees;

And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.

Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;

Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.
