Markus 3:9

3:9 Because of the crowd, he told his disciples to have a small boat ready for him so the crowd ¹  would not press toward him.

Markus 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 ²  had married her.

[3:9]  ¹ tn Grk “they”; the referent (the crowd) has been specified in the translation for clarity.

[6:17]  ² tn Grk “he”; here it is necessary to specify the referent as “Herod,” since the nearest previous antecedent in the translation is Philip.
