{Mending their nets} (katartizontas ta diktua aut(936e)).
These two brothers, James and John, were getting their nets ready
for use. The verb (katartiz(935c)) means to adjust, to articulate,
to mend if needed ( Lu 6:40  Ro 9:22  Ga 6:1 ). So they promptly
left their boat and father and followed Jesus. They had also
already become disciples of Jesus. Now there are four who follow
him steadily.
