1 Corinthians 9:20

Verse 20. Unto the Jews I became as a Jew] In Acts 16:3, we find that for the sake of the unconverted Jews he circumcised Timothy. See the note there.

To them that are under the law] To those who considered themselves still under obligation to observe its rites and ceremonies, though they had in the main embraced the Gospel, he became as if under the same obligations; and therefore purified himself in the temple, as we find related, Acts 21:26, where also see the notes.

After the first clause, to them that are under the law as under the law, the following words, μη ων αυτος ὑπο νομον, not being myself under the law, are added by ABCDEFG, several others; the later Syriac, Sahidic, Armenian, Vulgate, and all the Itala; Cyril, Chrysostom, Damascenus, and others; and on this evidence Griesbach has received them into the text.
