Exodus 1:6

After the death of Joseph and his brethren and the whole of the family that had first immigrated, there occurred that miraculous increase in the number of the children of Israel, by which the blessings of creation and promise were fully realised. The words פּרוּ ישׁרצוּ (swarmed), and ירבּוּ point back to Gen 1:28 and Gen 8:17, and יעצמוּ to עצוּם גּוי in Gen 18:18. "The land was filled with them," i.e., the land of Egypt, particularly Goshen, where they were settled (Gen 47:11). The extra-ordinary fruitfulness of Egypt in both men and cattle is attested not only by ancient writers, but by modern travellers also (vid., Aristotelis hist. animal. vii. 4, 5; Columella de re rust. iii. 8; Plin. hist. n. vii. 3; also Rosenmller a. und n. Morgenland i. p. 252). This blessing of nature was heightened still further in the case of the Israelites by the grace of the promise, so that the increase became extraordinarily great (see the comm. on Exo 12:37).

We have here, I. God's kindness to Israel, in multiplying them exceedingly (Exo 1:1-7). II. The Egyptians' wickedness to them, 1. Oppressing and enslaving them (Exo 1:8-14). 2. Murdering their children (Exo 1:15-22). Thus whom the court of heaven blessed the country of Egypt cursed, and for that reason.

1:6-7 The long sojourn of Jacob’s family in Egypt was part of a divine design. God had told Abraham that his descendants could not receive the land of Canaan for 400 years—until the sin of the Canaanites had come to its full fruition (Gen 15:13-16). Even in Egypt, God’s promises were at work, and the descendants of aged Abraham and barren Sarah multiplied . . . greatly as God had said (Gen 15:5), because God blessed them (Ps 105:24).
