Easton's Bible Dictionary (1897)/Butler
Butler : Properly a servant in charge of the wine (Gen. 40:1-13; 41:9). The Hebrew word, mashkeh, thus translated is rendered also (plural) "cup-bearers" (1 Kings 10:5; 2 Chr. 9:4). Nehemiah (1:11) was cup-bearer to king Artaxerxes. It was a position of great responsibility and honour in royal households.
