Tobit, a righteous Israelite, remained faithful to God despite being in captivity under the Assyrian king Shalmaneser, continuing to follow God's law and care for his people. He became blind and prayed to God, who sent the angel Raphael to care for him and his future daughter-in-law Sarah, who was being tormented by a demon. Tobit's son Tobias traveled with Raphael to the region of the Medes, retrieved money, and married Sarah, using a fish's liver to ward off the demon. After the wedding, Tobias returned home with Raphael, restored his father's sight with the fish's gall, and celebrated with his family, ultimately leading to Tobit spending the rest of his life praising God and warning his family to serve the Lord.
