Markus 1:19

1:19 Going on a little farther, he saw James, the son of Zebedee, and John his brother in their ¹  boat mending nets.

Markus 12:31

12:31 The second is: ‘Love your neighbor as yourself.’ ²  There is no other commandment greater than these.”

[1:19]  ¹ 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).

[12:31]  ² sn A quotation from Lev 19:18.
