Mark 6:29

And when his disciples heard of it, they came and took up his corpse, and laid it in a tomb.

The verse records the close of John's violent martyrdom by beheading, when his disciples came, took up his body, and laid it in a tomb. The execution was ordered by Herod after the daughter of Herodias pleased him with her dance, and John's bleeding head was then brought in before Herod's guests. Herod had heard John preach and knew him to be a true prophet, yet having turned away from the truth he put him to death. He was horrified by the sight and troubled by guilt over what he had done, though his remorse faded as he continued in sin.

After John had been put to death, Herod later feared that Jesus was John risen from the dead. John was killed for reproving Herod's sin, having given a pointed message even though it cost him his life. News of his death reached Jesus and His disciples after their first missionary tour and brought them bitter sorrow and disappointment. Jesus knew that leaving John to die in prison severely tested their faith, leading them to question why He had not saved John, which deepened their unbelief.

John's death resulted from intemperance among men entrusted with great authority, whose impaired judgment and failure to act justly allowed the killing. So the birthday feast stands as a warning against pleasure-seeking and a lesson in Christian temperance. His enemies could take his life but could not destroy his soul, hope, or eternal life. His example shows that faithful warning must become more and more pointed even at the risk of life so that the people will not be deceived.
