When you beat down the fruit of your olive trees, do not go over them again; that shall go to the stranger, the fatherless, and the widow. When you gather the grapes of your vineyard, do not pick it over again; that shall go to the stranger, the fatherless, and the widow. Always remember that you were a slave in the land of Egypt; therefore do I enjoin you to observe this commandment.
- Deuteronomy 24:20-22

Learn to do good.
Devote yourselves to justice;
Aid the wronged.
Uphold the rights of the orphan;
Defend the cause of the widow.
- Isaiah 1:17

He upheld the rights of the poor and needy -
Then all was well.
- Jeremiah 22:16

Practice goodness and justice.
And constantly trust in your God.
- Hosea 12:7

Spare Me the sound of your hymns,
And let Me not hear the music of your lutes.
But let justice well up like water,
Righteousness like an unfailing stream.
- Amos 5:23-24

He who sows injustice shall reap misfortune;
His rod of wrath shall fail.
The generous man is blessed.
For he gives of his bread to the poor.
- Proverbs 22:8-9
