Easton
The use of the bath was very frequent among the Hebrews (Le 14:8; Nu 19:19, ect.). The high priest at his inauguration (Le 8:6), and on the day of atonement, was required to bathe himself (Le 16:4,24). The "pools" mentioned in Ne 3:15-16; 2Ki 20:20; Isa 22:11; Joh 9:7, were public bathing-places.
