Genesis 24:20. She hasted, and emptied her pitcher into the trough.
These troughs are placed near the wells for convenience in watering cattle. They are made of wood or stone. Sometimes a long stone block is hollowed out, from which a number of animals can drink at once; and sometimes the troughs are smaller, several of them lying about the same well, each so small as to accommodate only one animal at a time.
