Baptised for the Name
Mat 28:18a Yeshua came and spake unto the Twelve...
In this verse, the "Twelve" included Judas, the only Jewish apostle (the remaining eleven were Ephraimites). Consider these verses:
Luk 6:13-16 When day came, he called his students and chose from among them twelve to be known as emissaries: Simon (whom he named Kefa) and his brother Andrew; James and John, Philip and Bartholomew, Matthew and Thomas, James son of Alphaeus, and Simon (who was called the Patriot), Judas son of James, and Judas Iscariot, who became the traitor.
Joh 20:19,24,26 In the evening that same day, being the first week of the seven weeks of Shavout, when the students were gathered together behind locked doors out of fear of the Judean leaders, Yeshua came, stood in the middle and said, "Shalom aleikhem!" Now Thomas (the name means "twin"), one of the Twelve, was not with them when Yeshua came. A week later his students were once more in the room, and this time Thomas was with them. Although the doors were locked, Yeshua came, stood among them and said, "Shalom aleikhem!"
Luk 24:12-13,33 Kefa got up and ran to the tomb. Stooping down, he saw only the burial cloths and went home wondering what had happened. That same day, two of them were going toward a village about seven miles from Jerusalem, called Emmaus. They got up at once and went back to Jerusalem, where they found the eleven students (everyone except Thomas) gathered together with the others.
1Cor 15:3-5 For I passed on to you as most important what I also received: that the Messiah of Israel died for the sake of our sins according to the Scriptures, that He was buried, that He was raised on the third day according to the Scriptures, and that He appeared to Kefa, then to all twelve (including Judas Iscariot).
The parenthetical events of Mat 27:3-10 occurred between Act 1:9 and Act 1:11.
Judas was called the "son of perdition" in Joh 17:12 because Judas' father was a Pharisee, Joh 13:2 & Luk 7:36-45.
