Mark 6:27

6:27 So ¹  the king sent an executioner at once to bring John’s ²  head, and he went and beheaded John in prison.

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 ³  had married her.

[6:27]  ¹ tn Grk “And.” Here καί (kai) has been translated as “so” to indicate the implied result of previous action(s) in the narrative.

[6:27]  ² tn Grk “his”; the referent (John the Baptist) has been specified in the translation for clarity.

[6:17]  ³ tn Grk “he”; here it is necessary to specify the referent as “Herod,” since the nearest previous antecedent in the translation is Philip.
