Tobias Attacked by a Monstrous Fish
"And Tobias went forward, and the dog followed him, and he lodged the first night by the river of Tigris. And he went out to wash his feet, and behold a monstrous fish came up to devour him. And Tobias being afraid of him, cried out with a loud voice, saying: Sir, he cometh upon me. And the angel said to him: Take him by the gill, and draw him to thee. And when he had done so, he drew him out upon the land, and he began to pant before his feet. Then the angel said to him: Take out the entrails of the fish, and lay up his heart, and his gall, and his liver for thee: for these are necessary for useful medicines." Tobit 6:1-5 DRA
Tobias is attacked by a monstrous fish. The angel protects him and instructs him to save parts of the fish to use as medicine.
