Baths : The use of the bath was very frequent among the Hebrews (Leviticus 14:8; Numbers 19:19, etc.). The high priest at his inauguration (Leviticus 8:6), and on the day of atonement, was required to bathe himself (Leviticus 16:4,24). The "pools" mentioned in Nehemiah 3:15,16,2 Kings 20:20, Isaiah 22:11, John 9:7, were public bathing-places.
