Matthew 6:16

“Beware of doing your righteousness before men to be noticed by them; otherwise you have no reward with your Father who is in heaven.

“Therefore, when you give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be glorified by men. Truly I say to you, they have their reward in full.

“And when you pray, you are not to be like the hypocrites; for they love to stand and pray in the synagogues and on the street corners so that they may be seen by men. Truly I say to you, they have their reward in full.

“But they do all their deeds to be noticed by men; for they broaden their phylacteries and lengthen the tassels of their garments.
