You ignored it. Perhaps you didn't know. This is the risen Lord speaking to Paul.
Acts 22:
17 And it came to pass, that, when I was come again to Jerusalem, even while I prayed in the temple, I was in a trance;
18 And saw him saying unto me, Make haste, and get thee quickly out of Jerusalem: for they will not receive thy testimony concerning me.
19 And I said, Lord, they know that I imprisoned and beat in every synagogue them that believed on thee:
20 And when the blood of thy martyr Stephen was shed, I also was standing by, and consenting unto his death, and kept the raiment of them that slew him.
21 And he said unto me, Depart: for I will send thee far hence unto the Gentiles.
