John Lightfoot on Matthew 4:18

[Casting a net into the sea.] Fishing in the sea of Tiberias, in Talmudic speech. There the fathers of the traditions dream that Joshua the son of Nun gave ten laws to the Israelites concerning having some things in common, as lawful, and to be allowed of: Our Rabbins have a tradition that Joshua ordained ten conditions: That cattle graze in common in woody places. And that a man gather wood in common in his neighbour's field, &c. Among others, And that any, in common, spread his nets for fishing in the sea of Tiberias. But yet under this caution, That none set up a wall, which may be any stop to ships. The Gloss is, "It is the manner of fishermen to fasten stakes in the water, and to make fences of canes or reeds, in which the fish may be taken: but this is not permitted, because it is an impediment to the ships." However therefore the sea of Tiberias belonged to the tribe of Nephthali, yet it was free for any Israelite to fish in it, so it were under the condition mentioned.
