Genesis 15:13

Strangers, and under bondage, &c. This prediction may be dated from the persecution of Isaac by Ismael, in the year 2112, till the Jews left Egypt, 2513. In Exodus xii., and St. Paul, 430 years are mentioned; but they probably began when Abram went first into Egypt, 2084. Nicholas Abram and Tournemine say, the Hebrews remained in Egypt full 430 years. from the captivity of Joseph; and reject the addition of the Septuagint which adds, "they and their fathers dwelt in Egypt, and in Chanaan." On these points, we may expect to find chronologists at variance.
