Matthew Poole and continuators on Galatians 1:18

18 Then after three years, I went up to Jerusalem to see Peter, and abode with him fifteen dayes .

These three years were spent partly in Arabia, partly [illegible: 1 word] Damascus, whither he returned; and his being there, was not idle, but as Luke informes us, preached Christ in the Synagogues, Acts 9.20, 22, 26. confounded the Iewes, proving that this was the very Christ, which made the Iewes take counsel to kill him: Here it was that he escaped them, by being let down over the wall in a basket. Then he went to Ierusalem, where his Conversion, and call to preach the Gospel was not heard of, (possibly in regard of the remoteness of Arabia, where he had spent most of those three years; or in regard of the troubled state of the Church at Ierusalem at this time,) insomuch that the Disciples were afraid to admit him to join with them, until Barnabas had given Testimony concerning him, Acts 9.27. He tells us here that he stayed there but fifteen dayes; during which time, Luke Acts 9.29. tells us, he spake boldly in the name of the Lord Iesus, and disputed against the Grecians.
