{But it seemed good unto Silas to abide there} (edoxe de
Sil(8369) epimeinai autou). This verse is not in the Revised Version
or in the text of Westcott and Hort, being absent from Aleph A B
Vulgate, etc. It is clearly an addition to help explain the fact
that Silas is back in Antioch in verse  40 . But the "some days"
of verse  36  afforded abundant time for him to return from
Jerusalem. He and Judas went first to Jerusalem to make a report
of their mission.
