See Matthew 5:44-45.

But I say unto you which hear,.... The Ethiopic version adds "me", and the generality of interpreters understand the passage of the hearers of Christ, as distinct from the disciples, or together with them, and of the better sort of them; and of such as had ears to hear, and who heard with a desire of understanding, and of putting into practice what they heard; but I rather think it regards the hearers of the Scribes and Pharisees, then present, who had heard and received the traditions of the elders, to which the following rules of Christ are opposed; and to each of which, with others in Matthew, these words are prefixed;

ye have heard that it was said by them of old time--but I say unto you,.... Matthew 5:21 with which compare this phrase, and the sense will appear to be this; to you that hear day by day, the traditions of the elders urged upon you, and the false glosses the Scribes and Pharisees put upon the word of God; in opposition to them, I say to you what follows:

love your enemies; whereas you have heard them say, hate your enemies, keep enmity in your hearts to them, and revenge yourselves on them:

do good to them that hate you; whereas you have heard it said, that you should only do good to your friends, and should keep anger in your bosoms to such who hate you, and do you an injury; See Gill on Matthew 5:43, Matthew 5:44

Which hear

With the sense of hearing in order to heed: giving heed. Compare Matthew 11:15.

{5} But I say unto you which hear, Love your enemies, do good to them which hate you,

(5) Christian charity, which is very different from worldly charity, not only does not revenge injuries, but is even extended to our most grievous enemies, and that for our Father's sake who is in heaven: in well doing it is not at all seeking its own.

6:27-36 Love your enemies. These precepts are found in Matthew's report in their connection. See PNT Mt 5:44.

6:27 But I say to you that hear - Hitherto our Lord had spoken only to particular sorts of persons: now he begins speaking to all in general. Mt 5:44.

27-36. (See on [1585]Mt 5:44-48; [1586]Mt 7:12; and [1587]Mt 14:12-14.)

6:27-36 These are hard lessons to flesh and blood. But if we are thoroughly grounded in the faith of Christ's love, this will make his commands easy to us. Every one that comes to him for washing in his blood, and knows the greatness of the mercy and the love there is in him, can say, in truth and sincerity, Lord, what wilt thou have me to do? Let us then aim to be merciful, even according to the mercy of our heavenly Father to us.
