Acts 1:23

“And they appointed two, etc.] The motion made by Peter was attended to by the whole company; they approved of it, and accordingly proposed two persons by name; one of which was to be chosen, not by the apostles, but by the whole assembly. The Arabic version reads, “he appointed two”, as if Peter singly did this: contrary to all copies, and other versions, and to the context; which shows, that the whole body of the people were concerned in this affair, who prayed and gave forth their lots and suffrages: the persons nominated were, Joseph called Barsabas, who was surnamed Justus, and Matthias. The former of these has three names; in one ancient copy of Beza’s he is called Joses; and by some…”

“they appointed--"put up" in nomination; meaning not the Eleven but the whole company, of whom Peter was the spokesman. two--The choice would lie between a very few.”

“And they appointed two - They proposed, or, as we should say, nominated two. Literally, they placed two, or made them to stand forth, as persons do who are candidates for office. These two were probably-more distinguished by prudence, wisdom, piety, and age than the others, and they were so nearly equal in qualifications that they could not determine which was the best suited for the office. Joseph called Barsabas ... - It is not certainly known what the name Barsabas denotes. The Syriac word “Bar” means “son,” and the word “Sabas” has been translated “an oath, rest, quiet, or captivity.” Why the name was given to Joseph is not known but probably it was the family name - Joseph son of Sabas.…”

“And they appointed two - So far the faithful could go by consulting together, but no further. Therefore here commenced the proper use of the lot, whereby a matter of importance, which cannot be determined by any ordinary method, is committed to the Divine decision. Acts 1:25”

“1:23-26 With prayer (1:14, 24) and humble dependence on God to reveal his will, the apostles cast lots, using an established method of finding God’s will (see Lev 16:8; Num 27:21; Deut 33:8; Josh 14:2; 18:3-10; Prov 16:33). Matthias was selected to replace Judas. After Pentecost, the Holy Spirit guided Jesus’ followers through dreams, visions, and prophecies instead of through lots (cp. Acts 2:17-18; 13:2; 16:7-10). • you know every heart: See also 1 Sam 16:6-7; 1 Kgs 8:39; 1 Chr 28:9; 2 Chr 6:30; Pss 7:9; 44:21; Jer 11:20; John 2:24-25; Rev 2:23.”
