1 Kings 18:13
Was it not told my lord what I did when Jezebel slew the prophets of the LORD, how I hid an hundred men of the LORD’s prophets by fifty in a cave, and fed them with bread and water? Was it not told my lord what I did when Jezebel slew the prophets of the LORD, how I hid an hundred men of the LORD’s prophets by fifty in a cave, and fed them with bread and water?
The verse is set in Israel's apostasy, when Ahab had married the idolatrous Jezebel, who held more power over the king than God did and led him and the people into idolatry and Baal worship. God had sent Elijah to Israel with messages of warning, but neither king nor people would heed his words, regarding him as a messenger of evil. At last God sent a drought upon the land, but the people did not discern and acknowledge the object of this judgment nor humble their hearts before Him.
Jezebel pursued a wicked course of slaying the prophets of the LORD, charging that they had brought calamity and suffering on Israel by their reproofs and that there would be no rest or prosperity in the land until they were put to death. Thus anger was aroused against the men God had sent to entreat the people to repent of their wickedness, and many holy men died for their testimony. Elijah was preserved by a miracle of divine power to proclaim before the king and queen the warnings and threatenings of God.
In that apostasy Obadiah himself stayed faithful to God and remained faithful while Ahab worshiped Baal. At the risk of his life he protected one hundred of the LORD's prophets when their lives were in danger from Jezebel's persecution, hiding them in a cave in two groups of fifty and supplying them with bread and water. His actions thereby preserved faithful servants of God.
The verse belongs to the account of Elijah's work during Israel's idolatry and famine, including his confrontation with Ahab in which Elijah declares that Ahab and his father's house, not Elijah, have troubled Israel. The wider account teaches that Elijah's faith and courage on Mount Carmel did not prevent a later failure of faith when Jezebel threatened him, so that he fled and God appointed another prophet to complete the work. God nevertheless honored Elijah's faithful service and took him to heaven without his dying.
