Exodus 22:22 - Wesley's Explanatory Notes

Ye shall not afflict the widow or fatherless child — That is, ye shall comfort and assist them, and be ready upon all occasions to shew them kindness. In making just demands from them, their condition must be considered who have lost those that should protect them: they are supposed to be unversed in business, destitute of advice, timorous, and of a tender spirit; and therefore must be treated with kindness and compassion, and no advantage taken against them, nor any hardship put upon them, which a husband or a father would have sheltered them from.
