John Gill Commentary Luke 5:2

"and he saw two boats standing by the lake: but the fishermen had gone out of them, and were washing their nets." — Luke 5:2 (ASV)

And saw two ships standing by the lake
Or two fishing boats; which were, as the Arabic version renders it, "detained by anchors at the shore of the lake"; the one belonging to Peter and Andrew, and the other to Zebedee, and his two sons, James and John:

but the fishermen were gone out of them ;
that is, either the above persons, or their servants:

and were washing their nets ;
on shore; they having gathered a great deal of soil and filthiness, but had caught no fish; and therefore were cleansing their nets, in order to lay them up, finding it to be in vain to make any further attempts with them at present; and which considered, makes the following miracle the more illustrious.
