Mark 6:17

6:17 For Herod himself had sent men, arrested John, and bound him in prison on account of Herodias, his brother Philip’s wife, because Herod ¹  had married her.

Mark 6:28

6:28 He brought his head on a platter and gave it to the girl, and the girl gave it to her mother.

[6:17]  ¹ tn Grk “he”; here it is necessary to specify the referent as “Herod,” since the nearest previous antecedent in the translation is Philip.
