Crucifixion involved hanging a person from a cross or T In Crucifixion, the convict was hanged (crucified) and left to die. The text said, the convict was slain (slew) first, then hanged.. Acts 10:39 And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: The alleged contradiction between Acts 10:39 regarding what is recorded as having happened to Jesus is non-existent.
Firstly, the person who was crucified was impaled through the wrists in order to impose maximum pain by pinching the nerve that runs through there. Then they were also impaled through the legs and finally hoisted on high where they 'hung' in mid-air, naked and struggling for every breath. The word in Greek kremannumi means 'to hang' but not in the sense of hanging by the neck as a form of execution. It is also used in Luke 23:39 referring to another of those crucified with Jesus. Thus we see that using the verb that means 'to hang' is one word that can be used to describe what happened in crucifixion. Sometimes people would 'hang' on the cross for days before they died.
Secondly, the verse in Acts is not chronological but merely describes or lists what happened. Jesus most certainly was killed. Jesus most certainly did hang as part of that process. The order is immaterial to the fact in this case since everyone in those days knew that no-one would come down from the cross alive. One could say that Luke, in writing Acts was here emphasizing the death of Jesus as a definite occurrence first and the method of how it was done second.
