Easton's 1897 Bible Dictionary:
The use of the bath was very frequent among the Hebrews (Lev.
14:8; Num. 19:19, ect.). The high priest at his inauguration
(Lev. 8:6), and on the day of atonement, was required to bathe
himself (16:4, 24). The "pools" mentioned in Neh. 3:15, 16, 2
Kings 20:20, Isa. 22:11, John 9:7, were public bathing-places.
