“And all the souls that came out of the loins of Jacob were seventy souls: for Joseph was in Egypt already.”
King James Version (KJV)
Matthew Henry's Concise Commentary
1:1-7 During more than 200 years, while Abraham, Isaac, and Jacob lived at liberty, the Hebrews increased slowly; only about seventy persons went down into Egypt. There, in about the same number of years, though under cruel bondage, they became a large nation. This wonderful increase was according to the promise long before made unto the fathers. Though the performance of God's promises is sometimes slow, it is always sure.
“And thou shalt bring the meat offering that is made of these things unto the LORD: and when it is presented unto the priest, he shall bring it unto the altar.”
