Jeremiah 38:9-10

“Your royal Majesty, those men have been very wicked in all that they have done to the prophet Jeremiah. They have thrown him into a cistern and he is sure to die of starvation there because there is no food left in the city. Then the king gave Ebed Melech the Ethiopian the following order: “Take thirty men with you from here and go pull the prophet Jeremiah out of the cistern before he dies.”
