Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. 8For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life. (Galatians 6:7-8. ESV.)
1 Corinthians 15:33: Do not be deceived: "Bad company ruins good morals."

Job 4:8: As I have seen, those who plow iniquity and sow trouble reap the same.
James 3:18: And a harvest of righteousness is sown in peace by those who make peace.
