Acts 1:20-22

Quoting from Psalms 69:25; Psalms 109:8, Peter reported that the Holy Spirit, through David, had said the habitation of Judas, perhaps as Ash suggests referring to the Field of Blood, would become desolate and another would be chosen to take his office. So, Peter set forth certain qualifications necessary for one to be chosen to take the office of an apostle. He had to have been with the Lord from the time of the baptism of John to the ascension. He would especially need to be able to stand forth as a witness of the resurrection (Acts 1:20-22).
