John Wesley on 2 Samuel 15:20

Brethren - Thy countrymen the Gittites, ver.18. Mercy, &c. - Since I am now unable to recompense thy kindness and fidelity to me, my hearty prayer to God is, that he would shew to thee his mercy, in blessing thee with all sorts of blessings, and his faithfulness in making good all these promises which he had made, not to Israelites only, but to all true hearted proselytes, such as thou art.
