Matthew 6:3

Be careful that you don't do your charitable giving before men, to be seen by them, or else you have no reward from your Father who is in heaven.

Therefore when you do merciful deeds, don't sound a trumpet before yourself, as the hypocrites do in the synagogues and in the streets, that they may get glory from men. Most certainly I tell you, they have received their reward.

so that your merciful deeds may be in secret, then your Father who sees in secret will reward you openly.

When you pray, you shall not be as the hypocrites, for they love to stand and pray in the synagogues and in the corners of the streets, that they may be seen by men. Most certainly, I tell you, they have received their reward.
