Musar zu Rut 2:11

“A man shall not oppress his countryman” (Leviticus 25:17) - the verse is speaking about verbal oppression, like we discussed above. And our Rabbis, may their memory be blessed, said (Bava Metzia 58b), “[If] one is a penitent, [another] may not say to him, ‘Remember your earlier deeds.’ [If] one is the child of converts, [another] may not say to him, ‘Remember the deeds of your ancestors.’” And that which is stated (Exodus 22:20), “You shall not oppress a stranger or press him,” [is understood as] “You shall not oppress” him verbally; “or press him” with money. And the Torah warned in several places about oppression of the convert, for he forgot his [own] people and the house of his father, and came to seek refuge under the wings of the Divine Presence - like the matter that is stated (Ruth 2:11), “how you left your father and mother and the land of your birth and came to a people you had not known before”; and it is stated (Ruth 2:12), “May the Lord reward your deeds; may you have a full recompense from the Lord, the God of Israel, under whose wings you have sought refuge!” And there is a [relevant] parable about a gazelle that comes to a flock, and crouches with the sheep there. So the owner of the flock had compassion on it - since it left a broad pasture to stand in a narrow place.
