Deuteronomy 24:17

17 Do not deprive foreigners and orphans of their rights; and do not take a widow’s garment as security for a loan.

Deuteronomy 24:20

20 When you have picked your olives once, do not go back and get those that are left; they are for the foreigners, orphans, and widows.

With great blessing comes great responsibility. God is just and fair. He wants us to share his concern for widows, orphans and foreigners.
