"and your sojourner in your gates": This is a ger tzedek (a "righteous sojourner," one who has converted to Judaism.) But perhaps it is a ger toshav (a "resident sojourner," one who does not serve idols and who observes the seven Noachide laws)? (This cannot be, for) (23:12) "and the sojourner" already speaks of a ger toshav. How, then, am I to understand "and your sojourner"? As referring to a ger tzedek.
