Luke 5:5

5 and Simon answering said to him, `Master, through the whole night, having laboured, we have taken nothing, but at thy saying I will let down the net.'

Luke 5:5 Meaning and Commentary

Luke 5:5

And Simon answering said unto him, master
Or Rabbi, as the Syriac version renders it: he knew him to be the Messiah, the king of Israel, and a teacher sent from God:

we have toiled all the night, and have taken nothing;
which carries in it an objection to what Christ advised and directed to: they had been fishing that "night", which was the best time for catching fish; and they had been at it all the night, and had "laboured" hard; and were even "fatigued", and quite wearied out; and what was most discouraging of all, their labour was in vain; they had caught "nothing":

nevertheless at thy word I will let down the net;
which showed faith in Christ, and obedience to him: thus the faithful preachers of the Gospel, sometimes labour and toil in the ministry of the word a great while, with little or no success; and are discouraged from going on, and would be tempted to leave off, were it not for the commission and word of command they have received from Christ, which they dare not be disobedient to; and for the word of promise he has given them, to be with them, on which they depend.

Luke 5:5 In-Context

3 and having entered into one of the boats, that was Simon's, he asked him to put back a little from the land, and having sat down, was teaching the multitudes out of the boat.
4 And when he left off speaking, he said unto Simon, `Put back to the deep, and let down your nets for a draught;'
5 and Simon answering said to him, `Master, through the whole night, having laboured, we have taken nothing, but at thy saying I will let down the net.'
6 And having done this, they enclosed a great multitude of fishes, and their net was breaking,
7 and they beckoned to the partners, who [are] in the other boat, having come, to help them; and they came, and filled both the boats, so that they were sinking.
