Mark 6:16-17

6:16 But when Herod heard this, he said, “John, whom I beheaded, has been raised!” 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.

[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.
