Fishing at night. Galilee fishermen often have fished at night. They light their way with a blazing torch, and sighting fish they let fly their fishing spear, or fling their net into the sea.
But sometimes they fish all night with no results, as was the case with Simon Peter and his comrades. "Master, we have toiled all the night, and have taken nothing" (Luke 5:5).
