Deuteronomy 23:7

An Edomite; the children of Edom; only the Amalekites are excepted by God's particular order, and upon special reason, Deuteronomy 25:17. Thy brother, by Esau, Jacob's brother. Thou wast a stranger in his land, and didst receive habitation, protection, and provision from them a long time, which kindness thou must not forget for their following persecution. It is ordinary with great men and others, that one injury or offence blots out the remembrance of twenty courtesies; but God doth not deal so with us, nor will he have us to deal so with others, but commands us to overlook and forget injuries, and to remember kindnesses.
