Therefore when you give your alms, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have their reward.
All Commentaries on Matthew 6:2 Go To Matthew 6
Not that they had trumpets, but He means to display the greatness of their frenzy, by the use of this figure of speech, deriding and making a show of them hereby.
And well has He called them hypocrites for the mask was of mercy, but the spirit of cruelty and inhumanity. For they do it, not because they pity their neighbors, but that they themselves may enjoy credit; and this came of the utmost cruelty; while another was perishing with hunger, to be seeking vainglory, and not putting an end to his suffering.
It is not then the giving alms which is required, but the giving as one ought, the giving for such and such an end.
Having then amply derided those men, and having handled them so, that the hearer should be even ashamed of them, He again corrects thoroughly the mind which is so distempered: and having said how we ought not to act, He signifies on the other hand how we ought to act. How then ought we to do our alms?
