Acts 20:21

testifying, &c.… to the Greeks The Rev. Ver.omits "the" before both nouns, the Greek having no article. "Both to Jews and to Greeks." By "testifying" is meant "proclaiming the need of." And this message the Apostle would support by his own witness.

repentance … Christ By some MSS. the last word is omitted. Some have seen in these two clauses a reference to the character of the preaching, "repentance" indicating what was most needful for the Gentiles, and "faith toward our Lord" the demand made upon the Jews. This however seems fanciful, especially when we remember the Pentecostal sermon of St Peter (Acts 2:38) which was certainly addressed to Jews rather than Gentiles, "Repent, and be baptized every one of you."
