John Wesley on Leviticus 19:34

As one born among you - Either 1, as to the matters of common right, so it reacheth to all strangers. Or 2, as to church - privileges, so it concerns only those who were proselytes. Ye were strangers - And therefore are sensible of the fears, distresses, and miseries of such, which call for your pity, and you ought to do to them, as you desired others should do to you, when you were such.
