'Drinking' in the Bible

Wash thyself therefore, and anoint thee, and put thy raiment upon thee, and get thee down to the floor: but make not thyself known unto the man, until he shall have done eating and drinking.

After Boaz had finished eating and drinking to his heart's content, he went over and lay down next to the pile of threshed grain. Ruth came in quietly, uncovered his feet, and lay down.
