For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward: He doth execute the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment.
(Deuteronomy 10:17,18)

(Psalm 146:9)

(Proverbs 15:25)

(Isaiah 1:17)

Leave thy fatherless children, I will preserve them alive; and let thy widows trust in me.
(Jeremiah 49:11)

And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the stranger from his right, and fear not me, saith the LORD of hosts.
(Malachi 3:5)

(Matthew 23:14)

(Acts 6:1)

But if any widow have children or nephews, let them learn first to shew piety at home, and to requite their parents: for that is good and acceptable before God. Now she that is a widow indeed, and desolate, trusteth in God, and continueth in supplications and prayers night and day. But she that liveth in pleasure is dead while she liveth.
(1 Timothy 5:4-6)
