In four verses, the Bible cites God as requiring the Israelites to be especially considerate of persons who are in the status of 'Ger', because the Israelites themselves had been in such a status when they were in Egypt (Exodus 22:20; Exodus 23:9; Leviticus 19:34 and Deuteronomy 10:19). But who is the Ger to whom this mitzvah applies? The answer to this question has varied over the millennia.
