Jesus appointed the twelve apostles.

Mark 3:13-19

13 Jesus went with many other people up into the hills. After he picked out from among them the men whom he wanted to accompany him, they came close to him. 14 He appointed twelve men in order that they might be with him and in order that he might send them out to preach. He called them apostles. 15 He also gave them power in order that they might expel evil spirits from people. 16 These were the twelve men he appointed: Simon, to whom he gave the new name Peter; his younger brother Andrew; 17 James, the son of Zebedee, and John, the younger brother of James, to both of whom he added the new name, ‘Men who are like Thunder’. because of their fiery zeal; 18 Philip; Bartholomew; Levi, whose other name was Matthew; Thomas; another James, the son of Alphaeus; Thaddeus; another Simon, who was a member of the party that wanted to overthrow the Roman government; 19 and Judas Iscariot (OR, Judas, the man from Kerioth Town). He was the one who later ◄betrayed Jesus/helped Jesus’ enemies seize him►.
