John Wesley on Leviticus 25:47

The flock - Heb. root, that is, one of the root or flock. So the word root is elsewhere used for the branch or progeny growing from it. He seems to note one of a foreign race and country, transplanted into the land of Israel, and there having taken root amongst the people of God, yet even such an one, though he hath some privilege by it, shall not have power to keep an Hebrew servant from the benefit of redemption.
