RUTH WAS A NON-JEW WHO FOLLOWED TORAH

Leviticus 23:22 And when you reap the harvest of your land, you shall not make clean riddance of the corners of your field when you reap, neither shall you gather any gleaning of thy harvest: you shall leave them unto the poor, and to the stranger: I am the LORD your God.

Ruth 2:2 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.
