Moses
Deuteronomy 10:18ESV·traditional attribution

He executes justice for the fatherless and the widow, and loves the sojourner, giving him food and clothing.

Matthew Henry Presbyterian @wholebiblehenry

Here is a most pathetic exhortation to obedience, inferred from the premises, and urged with very powerful arguments and a great deal of persuasive rhetoric. Moses brings it in like an orator, with an appeal to his auditors And now, Israel, what doth the Lord thy God require of thee? Deu 10:12. Ask what he requires; as David (Psa 116:12), What shall I render?

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; Psa 68:5.

Keil & Delitzsch Lutheran @keilanddelitzsch

Deu 10:18-19 As such, Jehovah does justice to the defenceless (orphan and widow), and exercises a loving care towards the stranger in his oppression. For this reason the Israelites were not to close their hearts egotistically against the stranger (cf. Exo 22:20). This would show whether they possessed any love to God, and had circumcised their hearts (cf. 1Jo 3:10, 1Jo 3:17).
