While many translations read “sons of Israel” in Deut 32:8 (following the traditional Hebrew text’s reading of benei yisrael), “sons of God” (benei elohim in Hebrew) is the more probable original Hebrew reading based on manuscript evidence from the Dead Sea Scrolls (ca. 250 bc–ad 50). The Septuagint, the ancient Greek translation of the ot, also attests to reading “God,” not “Israel” for this verse.
