God knows what to do!
“And going into one of the ships that was Simon's, he desired him to
draw back a little from the land. And sitting, he taught the multitudes
out of the ship.
Now when he had ceased to speak, he said to Simon: Launch out into the deep and let down your nets for a draught.
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 when they had done this, they enclosed a very great multitude of fishes: and their net broke. “
