Matthew 6:1-4 NKJV
1 “Take heed that you do not do your charitable deeds before men, to be seen by them. Otherwise you have no reward from your Father in heaven.
2 Therefore, when you do a charitable deed, do not sound a trumpet before you as the hypocrites do in the synagogues and in the streets, that they may have glory from men. Assuredly, I say to you, they have their reward.
3 But when you do a charitable deed, do not let your left hand know what your right hand is doing,
4 that your charitable deed may be in secret; and your Father who sees in secret will Himself reward you openly.
