'Butler' in the Bible

And it cometh to pass, after these things -- the butler of the king of Egypt and the baker have sinned against their lord, against the king of Egypt;

And they dream a dream both of them, each his dream in one night, each according to the interpretation of his dream, the butler and the baker whom the king of Egypt hath, who are prisoners in the round-house.

yet, within three days doth Pharaoh lift up thy head, and hath put thee back on thy station, and thou hast given the cup of Pharaoh into his hand, according to the former custom when thou wast his butler.
