Deuteronomy 27:19

Cursed [be] he that perverteth the judgment of the stranger,
fatherless, and widow
Who have none to assist them, and take their part, and therefore judges may be tempted to do an unjust thing; but God is the patron of them, and takes notice of every injury done them, and is the avenger of all such: and all the people shall say Amen; (See Gill on Deuteronomy 27:15); (See Gill on Deuteronomy 27:16).
