Charles Ellicott Commentary Luke 5:4

"And when he had left speaking, he said unto Simon, Put out into the deep, and let down your nets for a draught." — Luke 5:4 (ASV)

Let down your nets.—It is, perhaps, a slight indication that St. Luke's narrative does not describe the same event as the other Gospels, in that they use a different word for "net," one that technically has quite a distinct meaning. St. Luke’s word, however, is generic and may therefore include the other; and the other two use it when they speak of the disciples leaving their "nets."
