And they gave forth their lots. — As interpreted by the prayer of Acts 1:24, and by the word “fell” here, there can be no doubt that the passage speaks of “lots” and not “votes.” The two men were chosen by the disciples as standing, as far as they could see, on the same level. It was left for the Searcher of hearts to show, by the exclusion of human will, which of the two He had chosen. The most usual way of casting lots in such cases was to write each name on a tablet, place them in an urn, and then shake the urn till one came out. A like custom prevailed among the Greeks, as in the well-known story of the stratagem of Cresphontes in the division of territory after the Doriar invasion (Sophocles, Aias. 1285; comp. Proverbs 16:33). The practice was recognised, it may be noted, in the Law (Leviticus 16:8).
He was numbered with the eleven apostles. — The Greek word is not the same as in Acts 1:17, and implies that Matthias was “voted in,” the suffrage of the Church unanimously confirming the indication of the divine will which had been given by the lot. It may be that the new Apostle took the place which Judas had left vacant, and was the last of the Twelve.
