Hebrews 12:13-17

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

Follow peace with all men, and holiness, without which no man shall see the Lord:

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.

For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
