Atos 7:6

And that they should bring them into bondage... — Here again there is another apparent discrepancy of detail. Taking the common computation, the interval between the covenant with Abraham and that with Moses was 430 years (Gálatas 3:17), of which only 215 are reckoned as spent in Egypt. The Israelites were indeed sojourners in a strange land for the whole 430 years, but the history shows that they were not in bondage nor evil entreated till the Pharaoh arose who knew not Joseph. The chronological difficulty, however, lies in reconciling St. Paul’s statement in Gálatas 3:17 with the language of Gênesis 15:13, which gives 400 years as the sojourning in Egypt, and Êxodo 12:40, which gives 430, and with which St. Stephen is in substantial agreement. St. Paul appears to have followed the LXX. reading of Êxodo 12:40, which inserts “in the land of Cannan,” and in some MSS. “they and their fathers,” and with this the Samaritan Pentateuch agrees. Josephus varies, in some passages (Ant. ii. 15, § 2), giving 215 years; in others (Ant. ii. 9, § 1; Wars, v. 9, § 4), 400. All that can be said is, as before, that chronological accuracy did not affect the argument in either case. It was enough for St. Stephen, as for St. Paul, to accept this or that system of dates, as they had been taught, without inquiring into the grounds on which it rested. Such inquiries were foreign to the Jewish character generally, and above all to that character when possessed by the sense of new and divine realities. Round numbers were enough for them to mark the successive stages of God’s dealings with His people.
