Where in bible is the martyredom of John the Baptist?

Answer 1

John Baptizer's death is discussed in the Gospel accounts of Matthew and Mark.

John was beheaded after a request was made of King Herod from Salome during his birthday celebration. Salome was the daughter Herodias who had a grudge against John because he denounced her relationship with Herod as immoral.

(Matthew 14:1-12) At that particular time Herod, the district ruler, heard the report about Jesus 2 and said to his servants: "This is John the Baptist. He was raised up from the dead, and this is why the powerful works are operating in him." 3 For Herod had arrested John and bound him and put him away in prison on account of He·ro′di·as the wife of Philip his brother. 4 For John had been saying to him: "It is not lawful for you to be having her." 5 However, although he wanted to kill him, he feared the crowd, because they took him for a prophet. 6 But when Herod's birthday was being celebrated the daughter of He·ro′di·as danced at it and pleased Herod so much 7 that he promised with an oath to give her whatever she asked. 8 Then she, under her mother's coaching, said: "Give me here upon a platter the head of John the Baptist." 9 Grieved though he was, the king out of regard for his oaths and for those reclining with him commanded it to be given; 10 and he sent and had John beheaded in the prison. 11 And his head was brought on a platter and given to the maiden, and she brought it to her mother. 12 Finally his disciples came up and removed the corpse and buried him and came and reported to Jesus.

(Mark 6:21-29) But a convenient day came along when Herod spread an evening meal on his birthday for his top-ranking men and the military commanders and the foremost ones of Gal′i·lee. 22 And the daughter of this very He·ro′di·as came in and danced and pleased Herod and those reclining with him. The king said to the maiden: "Ask me for whatever you want, and I will give it to you." 23 Yes, he swore to her: "Whatever you ask me for, I will give it to you, up to half my kingdom." 24 And she went out and said to her mother: "What should I ask for?" She said: "The head of John the baptizer." 25 Immediately she went in with haste to the king and made her request, saying: "I want you to give me right away on a platter the head of John the Baptist." 26 Although he became deeply grieved, yet the king did not want to disregard her, in view of the oaths and those reclining at the table. 27 So the king immediately dispatched a body guardsman and commanded him to bring his head. And he went off and beheaded him in the prison 28 and brought his head on a platter, and he gave it to the maiden, and the maiden gave it to her mother. 29 When his disciples heard of it they came and took up his corpse and laid it in a memorial tomb.
