Where did that come from?
You reap what you sow. This one is found throughout the Bible: "Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap" (Galatians 6:7)."Those who plow iniquity and sow trouble reap the same." (Job 4:8). "You have plowed wickedness; You have reaped iniquity." (Hosea 10:13). "He who sows iniquity will reap sorrow." (Proverbs 22:8). "For he who sows to the flesh will of the flesh reap corruption, but he who sows to the spirit will of the spirit reap everlasting life." (Galatians 6:8).
