2 tn Or “a boat.” The phrase ἐν τῷ πλοίῳ (en tw ploiw) can either refer to a generic boat, some boat (as it seems to do in Matt 4:21); or it can refer to “their” boat, implying possession. Mark assumes a certain preunderstanding on the part of his readers about the first four disciples and hence the translation “their boat” is justified (cf. also v. 20 in which the “hired men” indicates that Zebedee’s family owned the boats).
3 tn Grk “he”; here it is necessary to specify the referent as “Herod,” since the nearest previous antecedent in the translation is Philip.
