Adam Clarke on Acts 23:6

I am a Pharisee, the son of a Pharisee - Instead of Φαρισαιου, of a Pharisee, ABC, some others, with the Syriac and Vulgate, have Φαρισαιων, of the Pharisees; which, if acknowledged to be the genuine reading, would alter the sense thus, I am a Pharisee, and a disciple of the Pharisees, for so the word son is frequently understood.

Of the hope and resurrection - Concerning the hope of the resurrection, the και, and, being here redundant; indeed, it is omitted by the Syriac, all the Arabic, and Ethiopic. St. Paul had preached the resurrection of the dead, on the foundation and evidence of the resurrection of Christ. For this, he and the apostles were, some time before, imprisoned by the high priest and elders, Act 4:1-3; Act 5:17, because they preached, Through Jesus, the resurrection of the dead. This they could not bear; for, if Jesus Christ rose from the dead, their malice and wickedness, in putting him to death, were incontrovertibly established.
