<p>18:21 <i>B</i><i>ut took his leave of them, saying:<em> I will return again to you if God wills. </em></i><i>He then set sail from Ephesus</i>- Some texts add: &quot;Saying, I must by all means keep this feast that comes in Jerusalem&quot;. We sense here his obsession with getting to Jerusalem; see on :18. There is no evidence that Paul did in fact go up to Jerusalem as he planned at this stage. See on :22. His plans to go there were frustrated; it was the Lord's intention that Paul preach to the Gentiles and leave the Jews to Peter. And yet Paul still didn't get it; for he again pushes to go up to Jerusalem to keep a feast, Pentecost (19:21). The Holy Spirit warned him not to do this, but he still pushed ahead. The way his plans were frustrated at this earlier stage was surely a lesson he failed to heed.</p>
