Deuteronomy 14:28-29 "At the end of every third year you shall bring out the tithe of your produce of that year and store it up within your gates. And the Levite, because he has no portion nor inheritance with you, and the stranger and the fatherless and the widow who are within your gates, may come and eat and be satisfied, that the LORD your God may bless you in all the work of your hand which you do.
Deuteronomy 26:12-14 “When you have finished laying aside all the tithe of your increase in the third year—the year of tithing—and have given it to the Levite, the stranger, the fatherless, and the widow, so that they may eat within your gates and be filled, then you shall say before the LORD your God: ‘I have removed the holy tithe from my house, and also have given them to the Levite, the stranger, the fatherless, and the widow, according to all Your commandments which You have commanded me; I have not transgressed Your commandments, nor have I forgotten them. I have not eaten any of it when in mourning, nor have I removed any of it for an unclean use, nor given any of it for the dead. I have obeyed the voice of the LORD my God, and have done according to all that You have commanded me.
Psalm 68:5 A father of the fatherless, a defender of widows, Is God in His holy habitation.
Isaiah 1:23 Your princes are rebellious, And companions of thieves; Everyone loves bribes, And follows after rewards. They do not defend the fatherless, Nor does the cause of the widow come before them.
Jeremiah 5:28 They have grown fat, they are sleek; Yes, they surpass the deeds of the wicked; They do not plead the cause, The cause of the fatherless; Yet they prosper, And the right of the needy they do not defend.
