Commentaries:
Toiling for long hours trying to catch fish yet without results is especially exhausting and discouraging. Peter points out the obvious, but out of respect adds, "At Your word I will let down the net." Note that Jesus' command is for Peter to let down his "nets" (plural), yet he replies with "net" (singular). His obedience is half-hearted. Not completely understanding God's power in Jesus, he probably figures the result would be the same as his earlier lack of success. His unbelieving attitude exposes itself in poor-quality obedience. At this early stage, Peter is still learning about the power of the Creator to command His creation (John 1:3; Colossians 1:16).

In the account of Jesus' miracle of the great catch of fish (Luke 5:1-11), Luke calls the Sea of Galilee the "Lake of Gennesaret," a more ancient name that derives from the name of a small plain on its western shore. On this occasion, while standing in the boat in which Simon Peter had spent the whole—and very unsuccessful—night fishing, Jesus teaches those who wanted to hear the Word of God. Afterward, He tells Simon, "Launch out into the deep and let down your nets for a catch." The man's reply is typical of an experienced fisherman: "Master, we have toiled all night and caught nothing." Shortly afterward, however, he changes his tune.
