But when you give alms, let not your left hand know what your right hand does:
All Commentaries on Matthew 6:3 Go To Matthew 6
Chromatius of Aquileia
AD 407
Here the Lord is not speaking literally of the hands of the human body. Hands as such cannot know, having the senses neither of seeing nor or language. Rather, “on the right hand” means righteous deeds and “on the left” signifies sinful deeds or persons. Thus we read it written in the book of Kings that “hand” means people when it says, “Do I not have ten hands in Israel?”—that is, ten tribes of Israel. Therefore, there is no doubt that “on the right hand” means “the just” and “on the left” means “sinners,” according to what Solomon related: “The Lord acknowledges the divisions on the right; the perverse are those who are on the left.” The Lord makes very plain the meaning of this “right” and “left” in the Gospel when he declares that the just are to be placed at the right, the sinners on the left. If something is to be accomplished according to the teaching of the Lord, then the right hand of the just must not know what the left is doing. That is, in order to labor religiously and faithfully, we should not boast in the sight of sinners and unfaithful people. .
