Everyone here has a write-up, drawn from the same records that explain the names while you read the text.
Daniel
Major prophetTaken young into the Babylonian court, Daniel rose by wisdom and unbending faith, refusing the king's food, reading dreams and the writing on Belshazzar's wall, and emerging unharmed from the lions' den. His later visions map the rise and fall of empires to the end.
Jesus
The ChristThe carpenter from Nazareth whom the New Testament proclaims as the Messiah promised to Israel and the Son of God. He taught for roughly three years in Galilee and Judea, was executed under Pontius Pilate, and was raised on the third day. Christians across every tradition confess him as fully God and fully man, the formula the Council of Chalcedon settled on in 451.
MatthewMarkLuke
John the Baptist
ForerunnerA prophet in camel's hair who preached repentance at the Jordan and baptized Jesus. He named himself the voice crying in the wilderness from Isaiah, and was beheaded by Herod Antipas for condemning the king's marriage.
Matthew 3Matthew 11:2-19Mark 1:4-9
Peter
ApostleA Galilean fisherman who spoke first and thought later, walked on water and sank, confessed Jesus as the Christ, denied him three times, and was restored on a beach over breakfast. He preached the sermon at Pentecost and opened the door of the church to Gentiles at Cornelius' house.
Matthew 16:13-19Mark 1:16-18Luke 22:54-62
John
ApostleA fisherman called with his brother James, part of the inner three, and traditionally the author of the fourth Gospel, three letters, and Revelation. The Gospel calls him the disciple Jesus loved and places him at the cross, entrusted with Jesus' mother.
Mark 1:19-20John 19:26-27Acts 3:1-11
Judas Iscariot
Apostle who betrayed JesusOne of the twelve, who kept the money box and sold Jesus for thirty pieces of silver, then threw the money back into the temple and hanged himself. The Gospels report his motives sparingly and do not speculate.
Matthew 26:14-16Matthew 27:3-10Mark 14:10-11
Herod Antipas
Ruler of GalileeA son of Herod the Great, ruling Galilee through the whole of Jesus' ministry. He imprisoned John the Baptist for condemning his marriage, had him beheaded on the strength of a rash oath at a birthday party, and later heard about Jesus and wanted to see a miracle. When Pilate sent Jesus to him, he got nothing and sent him back.
Mark 6:14-29Luke 13:31-32Luke 23:6-12
Herodias
Wife of Herod AntipasShe held a grudge against John the Baptist for calling her marriage unlawful, and used her daughter's dancing and her husband's oath to get his head on a platter. Mark notes that Herod himself had feared John and liked to listen to him, which makes the manipulation the point.
Mark 6:17-28
Joseph of Arimathea
Council member and secret discipleA wealthy member of the council who had not consented to its decision. He went to Pilate and asked for the body, which took nerve, and buried Jesus in his own new tomb. All four Gospels record it.
Matthew 27:57-60Mark 15:42-46John 19:38
Bartimaeus
Blind beggar of JerichoHe shouted for the Son of David and was told to be quiet, so he shouted louder. Mark records that he threw off his cloak, which for a beggar was the thing he collected coins on, and jumped up. Asked what he wanted, he said he wanted to see.
Mark 10:46-52
The Syrophoenician woman
Who argued and wonA Gentile mother who asked Jesus to free her daughter and was answered with a hard saying about not giving the children's bread to the dogs. She took the image and turned it: even the dogs under the table eat the crumbs. It is the only exchange in the Gospels where someone answers Jesus back and is commended for it.
Mark 7:24-30Matthew 15:21-28
Jairus
Synagogue rulerA respected official who fell at Jesus' feet begging for his dying daughter, then had to stand through a delay while a woman in the crowd was healed, and heard while waiting that the girl had died.
Mark 5:21-43
Joseph of Nazareth
Husband of MaryA craftsman of Nazareth, betrothed to Mary, who was told in a dream to take her as his wife despite a pregnancy that was not his. He named the child, which in that culture was the act of claiming him as a son, and it is through Joseph that Jesus is legally of David's line.
Matthew 1:18-25Matthew 2:13-23Mark 6:3
Andrew
The rest of the TwelveThe apostles the gospels say least about. Andrew, Peter's brother, is the one who keeps bringing people to Jesus: his brother, the boy with the loaves, the Greeks who came asking. Thomas is remembered for one sentence of doubt and forgotten for another, let us also go, that we may die with him.
Matthew 10:2-4Mark 3:16-19Luke 6:14-16
Zebedee
Families of the disciplesThe fathers, mothers, and relatives named around the Twelve. Zebedee is left in the boat with the hired men when James and John walk away from the family fishing business, a detail Mark includes without comment.
Matthew 4:21-22Matthew 20:20-23Mark 1:19-20
Matthew
Apostle and tax collectorThe tax collector called from his booth at Capernaum, on the road running from Damascus to the coast. Mark and Luke call him Levi; Matthew's gospel calls him Matthew and adds the detail that he was a tax collector, which the others leave out of the apostle list.
Matthew 9:9-13Mark 2:13-17Luke 5:27-32
Ahimelech
Priest at NobThe priest who gave David the consecrated bread and Goliath's sword, not knowing he was a fugitive. Doeg the Edomite reported it, and Saul had eighty-five priests killed along with the whole town. Only Abiathar escaped.
1 Samuel 21:1-91 Samuel 22:9-232 Samuel 8:17
James
Three men of this nameJames son of Zebedee, John's brother, one of the inner three, and the first apostle martyred, killed by Herod Agrippa. James son of Alphaeus, of whom almost nothing is recorded. And James the brother of Jesus, who did not believe during the ministry and became the leader of the Jerusalem church.
Matthew 4:21Mark 3:17Luke 6:14-16
