Deuteronomy 24:19 Deut. 24:19
When thou cuttest down thine harvest in thy field, and hast forgot a sheaf in the field, thou shalt not go again to fetch it: it shall be for the stranger, for the fatherless, and for the widow: that the LORD thy God may bless thee in all the work of thine hands.
Ruth 2:2-7 Ruth 2:2-7
2 And Ruth the Moabitess said unto Naomi, Let me now go to the field, and glean ears of corn after him in whose sight I shall find grace. And she said unto her, Go, my daughter. 3 And she went, and came, and gleaned in the field after the reapers: and her hap was to light on a part of the field belonging unto Boaz, who was of the kindred of Elimelech. 4 And, behold, Boaz came from Bethlehem, and said unto the reapers, The LORD be with you. And they answered him, The LORD bless thee. 5 Then said Boaz unto his servant that was set over the reapers, Whose damsel is this? 6 And the servant that was set over the reapers answered and said, It is the Moabitish damsel that came back with Naomi out of the country of Moab: 7 And she said, I pray you, let me glean and gather after the reapers among the sheaves: so she came, and hath continued even from the morning until now, that she tarried a little in the house.
Deuteronomy 25:5-6 Deut. 25:5-6
5 If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her. 6 And it shall be, that the firstborn which she beareth shall succeed in the name of his brother which is dead, that his name be not put out of Israel.
Ruth 4:10 Ruth 4:10
Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.
