And Simon answering said to him: Master, we have laboured all the night, and have taken nothing: but at thy word I will let down the net.

“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.”

“Simon - said - Master - ΕπιϚατα. This is the first place where this word occurs; it is used by none of the inspired penmen but Luke, and he applies it only to our blessed Lord. It properly signifies a prefect, or one who is set over certain affairs or persons: it is used also for an instructer, or teacher. Peter considered Christ, from what he had heard, as teacher of a Divine doctrine, and as having authority to command, etc. He seems to comprise both ideas in this appellation; he listened attentively to his teaching, and readily obeyed his orders. To hear attentively, and obey cheerfully, are duties we owe, not only to the sovereign Master of the world, but also to ourselves. No man ever took Jesus profitably for his teacher, who did not at the same time receive him as his Lord. We have toiled all the night - They had cast the net several times in the course of the night, and drew it to shore without success, and were now greatly disheartened. I have seen several laborious draughts of this kind made without fruit. All labor must be fruitless where the blessing of God is not; but especially that of the ministry. It is the presence and influence of Christ, in a congregation, that cause souls to be gathered unto himself: without these, whatever the preacher's eloquence or abilities may be, all will be night, and fruitless labor. At thy word I will let down the net - He who assumes the character of a fisher of men, under any authority that does not proceed from Christ, is sure to catch nothing; but he who labors by the order and under the direction of the great Shepherd and Bishop of souls, cannot labor in vain.”

“Though these words of St. Peter seem to express his little hope of success, as he had been toiling ( kopiasantes ) the whole night, the most favourable time for fishing, yet they were intended by St. Peter to shew his great confidence, that notwithstanding his bad success, he was willing to obey; he relied on his words, and let go his net in the same place where before he had been disappointed; and the event proved that the obedience and confidence of Peter were not in vain. (Maldonatus, &c.)”

“Master--betokening not surely a first acquaintance, but a relationship already formed. all night--the usual time of fishing then (Joh 21:3), and even now Peter, as a fisherman, knew how hopeless it was to "let down his net" again, save as a mere act of faith, "at His word" of command, which carried in it, as it ever does, assurance of success. (This shows he must have been already and for some time a follower of Christ.)”
