Matthew 6:1-4
Modern English Version
Teaching About Charitable Giving
6 “Be sure that you not do your charitable deeds before men to be seen by them. Otherwise you have no reward from your Father who is in heaven.
2 “Therefore, when you do your charitable deeds, do not sound a trumpet before you as the hypocrites do in the synagogues and in the streets, that they may be honored by men. Truly I say to you, they have their reward. 3 But when you do your charitable deeds, do not let your left hand know what your right hand is doing, 4 that your charitable deeds may be in secret. And your Father who sees in secret will Himself reward you openly.
