Olive press from ancient times. The word Gethsemane means: the garden of the oil press. They would put the olives in baskets and stack them one on top of the other, then turn the press to push down the baskets to squeeze out the oil. You could press them up to seven times. The first 3 pressings were edible. The next four pressings could be used for cooking, medical treatment, oil for lamps & annointing oil.
