King James Version (KJV)

Acts 20:21

“Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.”

Verse in context — Acts 20

Serving the Lord with all humility of mind, and with many tears, and temptations, which befell me by the lying in wait of the Jews:

[And] how I kept back nothing that was profitable [unto you], but have shewed you, and have taught you publickly, and from house to house,

Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.

And now, behold, I go bound in the spirit unto Jerusalem, not knowing the things that shall befall me there:

Save that the Holy Ghost witnesseth in every city, saying that bonds and afflictions abide me.

The birth and growth of the early church through the power of the Holy Spirit.
