threescore and ten: Threescore and six were before mentioned (Genesis 46:26), so that Joseph and his two sons, together with Jacob himself, complete the seventy persons here enumerated; and the number in Genesis 46:15, Genesis 46:18, Genesis 46:22, and Genesis 46:25 amount to that number.
The addition of five persons in the LXX in Genesis 46:20, was either the cause or the consequence of another difference here; for in that version the number is seventy-five (Genesis 46:15, Genesis 46:18, Genesis 46:22, Genesis 46:25).
