And he spake boldly in the name of the Lord Jesus, and disputed against the Grecians: but they went about to slay him. Disputed against the Grecians - That is, the Hellenistic Jews, viz. those who lived in Grecian cities, spoke the Greek language, and used the Septuagint version for their scriptures. And thus the Syriac version has interpreted this place. See the note on Acts 6:1, where this subject is largely explained.
