John Gill Commentary Deuteronomy 10:18

"He doth execute justice for the fatherless and widow, and loveth the sojourner, in giving him food and raiment." — Deuteronomy 10:18 (ASV)

He doth execute the judgment of the fatherless and widow

Who have none to help them, and whose patron and defender he is, and will do them justice himself, and take care that it is done them by others, or avenge their injuries, for he is a Father of the fatherless, and a judge of the widow, in his holy habitation; (Psalms 68:5)

and loveth the stranger, in giving him food and raiment ;

one that is in a foreign country, at a distance from his native land, and destitute of friends; such God in his providence takes care of, and expresses his love and kindness to, by giving them the necessaries of life, food, and raiment.
