Matthew 14:5 ASV

³  For Herod had laid hold on John, and bound him, and put him in prison for the sake of Herodias, 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 came, the daughter of Herodias danced in the midst, and pleased Herod.

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