Ephesians 4:28-30

Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need. ²⁹ Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear. ³⁰ And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.
