Matthew
Matthew 6:2ESV·traditional attribution

“Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward.

John Calvin Reformed @genevareformer

2. When thou doest alms He expressly reproves a long established custom, in which the desire of fame might not only be perceived by the eye, but felt by the hands. In places where streets or roads met, and in public situations, where large assemblies were wont to be held, they distributed alms to the poor.

Matthew Henry Presbyterian @wholebiblehenry

As we must do better than the scribes and Pharisees in avoiding heart-sins, heart-adultery, and heart-murder, so likewise in maintaining and keeping up heart-religion, doing what we do from an inward, vital principle, that we may be approved of God, not that we may be applauded of men; that is, we must watch against hypocrisy, which was the leaven of the Pharisees, as well as against their doctrine, Luk 12:1.

John Gill Reformed Baptist @doctorgill

Wherefore, when thou dost thine alms,.... Christ proceeds to give some directions and cautions about giving of alms, that they might be done aright, and answer some valuable purposes for the glory of God, the good of others, and their own: do not sound a trumpet before thee, as the hypocrites do, in the synagogues, and in the streets, that they may have glory of men.
