While the disciples waited in Jerusalem for the fulfillment of the Lord’s promise to send the Holy Spirit, Peter addressed the need to appoint another to fill the office of Judas Iscariot.
The reason for the need was to fulfill prophecies found in the book of Psalms (69:25;109:8). The prophecies were general, concerning the enemies of David, but the Holy Spirit intended a special fulfillment in the events surrounding the Christ. There would be a need for someone to the chosen as Judas’ successor.
You may notice that verses 18-19 are parenthetical, supplied by Luke to explain the death of Judas. While Judas did not personally purchase the field where he committed suicide, it was purchased with the money he obtained by betraying the Lord. Thus Luke’s explanation surrounding the gruesome end of Judas Iscariot.
In verse 15, Peter stood among 120 disciples. These were not the only believers in the Lord (see 1 Corinthians 15:6 where we are told that over 500 believers had seen the resurrected Lord). But, these were the disciples present with the apostles as they awaited their promise. In verses 21-26 we will see how the successor was chosen.
