Matthew
Matthew 6:5BSB·traditional attribution

And when you pray, do not be like the hypocrites. For they love to pray standing in the synagogues and on the street corners to be seen by men. Truly I tell you, they already have their full reward.

John Gill Reformed Baptist

And when thou prayest, thou shalt not be as the hypocrites,.... As the Scribes and Pharisees; whose posture in prayer, the places they chose to pray in, and the view they had therein, are particularly taken notice of: for they love to pray standing in the synagogues, and in the corners of the streets, that they may be seen of men.

William Burkitt Anglican

Here our Saviour warns his disciples against the same Pharisaical hypocrisy in praying, which he had before reproved in almsgiving. It was lawful to pray in the synagogues, and to pray standing, and that before men; but to do this upon design to be applauded by men, is condemned by Christ.

John Calvin Reformed

5. When thou shalt pray He now gives the same instruction as to prayer, which he had formerly given as to alms. It is a gross and shameful profanation of the name of God, when hypocritcs, in order to obtain glory from men, pray in public, or at least make a pretense of praying. But, as hypocrisy is always ambitious, we need not wonder that it is also blind.
