Acts 1:14

These all with one accord continued stedfastly in prayer, with the women, and Mary the mother of Jesus, and with his brethren.

As Boles noted, "There are four separately mentioned classes of persons"[21] who made up this company. They were (1) the apostles, (2) Mary the mother of Jesus and certain other devout women, (3) the brothers of Jesus, and (4) certain other disciples (Acts 1:15).

In prayer ... No better way of waiting God's promise could be imagined than that followed here.

Mary the mother of Jesus ... This is the last mention of the Blessed Mary in the New Testament; and, from the fact of her being here with the apostles, it is evident that John honored the Lord's commission to receive her into his home and care for her (John 19:27).

And with his brethren ... The brothers of Jesus were James, and Joses, and Simon, and Judas (Matthew 13:55); and from the fact of their being mentioned apart from the apostles, it is clear that those apostles bearing some of these same names were not brothers of the Lord. As maintained throughout this series of commentaries, these brethren were the literal half-brothers of our Lord, being sons of Mary born after the birth of Jesus.

CHOOSING A SUCCESSOR TO JUDAS (Acts 1:15-26)

One of the most significant passages in the New Testament is this, wherein a successor to an apostle was chosen, the same being the only example of any such thing in the whole New Testament.
