While waiting, according to the commandment, for the promised power from on high, the disciples, under the leading of Peter (constituted chief in the Jewish ministry, Luke 22:32; John 21:16), commit it to the Lord to fill up the vacant bishopric of Judas. This was needful, as I shall observe more particularly by-and-by, that the Jewish order of twelve Apostles might stand full and complete; and that this was done with the full intelligence of the mind of God, appears further from this—that the Lord seems at once to undertake what His servants thus commit to Him, for He honors the lot (the Jewish form of discovering the Divine will in such matters, 1 Chron. 24:5; Num. 26:55; Josh. 19:10), and Matthias is numbered with the eleven Apostles; and the Holy Spirit in the next chapter seems to adopt Matthias in his new office, by falling upon him equally with the rest without any rebuke.
