Acts 7:14  7:14 seventy-five persons. The Hebrew text of Ex. 1:5
has “seventy.” But the Greek translation of the Old Testament
text, which this sermon is basically following, and the
fragments of Exodus found among the Dead Sea Scrolls read
“seventy-five.” The explanation of the “seventy-five” is to be
found in the five additional descendants of Joseph included in
the Greek translation of Gen. 46:20, where two sons of Manasseh,
two sons of Ephraim, and one grandson of Ephraim are included.
