Now let's examine the assumption we noted above: "both' is limited to Jerusalem and Judea; Samaria unto the ends of the land (or to the dispersion).
"And when they were come in, they went up into an upper room, where abode both Peter, and James, and John and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alphaeus and Simon Zelotes, and Judas the brother of James
-Acts 1:13
καὶ ὅτε εἰσῆλθον ἀνέβησαν εἰς τὸ ὑπερῷον οὗ ἦσαν καταμένοντες ὅ τε πέτρος καὶ ἰάκωβος καὶ ἰωάννης καὶ ἀνδρέας φίλιππος καὶ θωμᾶς βαρθολομαῖος καὶ ματθαῖος, ἰάκωβος ἁλφαίου καὶ σίμων ὁ ζηλωτὴς καὶ ἰούδας ἰακώβου
And then they went up to who lived both Peter and Jacob [James] and John and Andrew Philip and Thomas, Bartholomew and Matthew, Jacob Alphaeus and Simon the Zealot, and Judas Jacob
And in the Revised Version:
and when they had entered, they went up to the upper room, where they were staying, [both] Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus and Simon the Zealot and Judas the son of James
Notice the groupings:
- Peter and John
- James and Andrew
- Philip and Thomas
- Bartholomew and Matthew,
- James and Simon
- and Judas
Now when the apostles who were at Jerusalem heard that Samaria had received the word of God, they sent Peter and John to them, who, when they had come down, prayed for them that they might receive the Holy Spirit.
-Acts 8:14-15 (NKJV)
We will look, next time, a little more closely at the believing Gentiles in Caesarea. It is important to note Peter's calling, the region of Caesarea, the events in that house, and the reaction of the Jews.
But I digress. Peter and John are a group unto themselves in Acts 1. We God dealing in pairs much in the ministry of the Gospel accounts and in the Acts Age, The Lord sent the 70 out two-by-two.
After these things the Lord appointed seventy others also, and sent them two by two before His face into every city and place where He Himself was about to go.
-Luke 10:1 (NKJV)
We can see this in Paul's ministry as well (Paul and Barnabas then Paul and Silas).
