Paul Speaks to the Ephesian Elders
Act 20:17 And from Miletus he sent to Ephesus, and called the elders of the church.
Act 20:18 And when they were come to him, he said unto them, Ye know, from the first day that I came into Asia, after what manner I have been with you at all seasons,
Act 20:19 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:
Act 20:20 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,
Act 20:21 Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.

Act 20:23 Save that the Holy Ghost witnesseth in every city, saying that bonds and afflictions abide me.

Act 20:31 Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
