Matthew 14:5

³  For Herod had laid hold on John, and bound him, and put him in prison for Herodias' sake, his brother Philip's wife.

⁴  For John said unto him, It is not lawful for thee to have her.

⁵  And when he would have put him to death, he feared the multitude, because they counted him as a prophet.

⁶  But when Herod's birthday was kept, the daughter of Herodias danced before them, and pleased Herod.

⁷  Whereupon he promised with an oath to give her whatsoever she would ask.
