If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink:

Wesley's Notes

25:21 Bread - By bread and water he understands all things necessary for his subsistence.

Jamieson-Fausset-Brown Bible Commentary

21, 22. (Compare Mt 5:44; Ro 12:20). As metals are melted by heaping coals upon them, so is the heart softened by kindness.

Matthew Henry's Concise Commentary

25:19. Confidence in an unfaithful man is painful and vexatious; when we put any stress on him, he not only fails, but makes us feel for it. 20. We take a wrong course if we think to relieve those in sorrow by endeavouring to make them merry. 21,22. The precept to love even our enemies is an Old Testament commandment. Our Saviour has shown his own great example in loving us when we were enemies. 23. Slanders would not be so readily spoken, if they were not readily heard. Sin, if it receives any check, becomes cowardly. 24. It is better to be alone, than to be joined to one who is a hinderance to the comfort of life. 25. Heaven is a country afar off; how refreshing is good news from thence, in the everlasting gospel, which signifies glad tidings, and in the witness of the Spirit with our spirits that we are God's children! 26. When the righteous are led into sin, it is as hurtful as if the public fountains were poisoned. 27. We must be, through grace, dead to the pleasures of sense, and also to the praises of men. 28. The man who has no command over his anger, is easily robbed of peace. Let us give up ourselves to the Lord, and pray him to put his Spirit within us, and cause us to walk in his statutes.
