Galatians 3:24

“Wherefore the law was our schoolmaster unto Christ, etc..] So the words should be read, as they are by the Syriac and Ethiopic versions; for the words “to bring us” are a supplement of our translators, and have nothing to answer to them in the original; and the sense of the passage is, that the law performed this office of a schoolmaster until the coming of Christ; which shows that till that time the church was in its minority, that the Jews were but children in knowledge and understanding, and therefore stood in need, and were under the care of a schoolmaster, the law, by which the whole Mosaic administration is designed.
