Acts 1:21-22
21. all the time the Lord Jesus went in and out among us—in the close intimacies of a three years' public life.
22. Beginning from the baptism of John—by whom our Lord was not only Himself baptized, but first officially announced and introduced to his own disciples.
unto that same day when he was taken up from us, must one be ordained to be a witness with us of his resurrection—How clearly is the primary office of the apostles here expressed: (1) to testify, from personal observation, to the one great fact of "the resurrection of the Lord Jesus"; (2) to show how this glorified His whole previous life, of which they were constant observers, and established His divine claims.Acts 1:24-26
24. prayed and said, Thou, Lord, &c.—"The word 'Lord,' placed absolutely, denotes in the New Testament almost universally THE SON; and the words, 'Show whom Thou hast chosen,' are decisive. The apostles are just Christ's messengers: It is He that sends them, and of Him they bear witness. Here, therefore, we have the first example of a prayer offered to the exalted Redeemer; furnishing indirectly the strongest proof of His divinity" [OLSHAUSEN].
which knowest the hearts of all men—See Joh 2:24, 25; 21:15-17; Re 2:23.25. that he might go to his own place—A euphemistic or softened expression of the awful future of the traitor, implying not only destined habitation but congenial element.
26. was numbered—"voted in" by general suffrage.
with the eleven apostles—completing the broken Twelve.1 Timothy 5:22
22. Lay hands—that is, ordain (1Ti 4:14; 2Ti 1:6; Tit 1:5). The connection is with 1Ti 5:19. The way to guard against scandals occurring in the case of presbyters is, be cautious as to the character of the candidate before ordaining him; this will apply to other Church officers so ordained, as well as to presbyters. Thus, this clause refers to 1Ti 5:19, as next clause, "neither be partaker of other men's sins," refers to 1Ti 5:20. ELLICOTT and WIESINGER understand it of receiving back into Church fellowship or absolution, by laying hands on those who had been "rebuked" (1Ti 5:20) and then excommunicated (Mt 18:17); 1Ti 5:20 favors this. But as in 1Ti 4:14, and Ac 6:6; 13:3; 2Ti 1:6, the laying on of hands is used of ordination (compare however as to confirmation, Ac 8:17), it seems better to take it so here.
suddenly—hastily: 1Ti 5:24, 25 show that waiting for a time is salutary. neither be partaker of other men's sins—by negligence in ordaining ungodly candidates, and so becoming in some degree responsible for their sins. Or, there is the same transition from the elders to all in general who may sin, as in 1Ti 5:19, 20. Be not a partaker in other men's sins by not "rebuking them that sin before all," as well as those that are candidates for the presbytery, as also all "that sin." keep thyself pure—"thyself' is emphatic. "Keep THYSELF" clear of participation in OTHER men's sin by not failing to rebuke them that sin (1Ti 5:20). Thus the transition is easy to 1Ti 5:23, which is concerning Timothy personally; compare also 1Ti 5:24.
