Ezekiel 40:38  (King James Version)
And the chambers and the entries thereof were by the posts of the gates, where they washed the burnt offering.

the chambers
12 ; Ezekiel 41:10 Ezekiel 41:11 1 Kings 6:8

This place, where the legs and entrails of the sacrifices, especially of the burnt offerings, were washed, was just within the portico of the north entrance to the inner court, or court of the priests. An allusion to this is most probably made by the inspired apostle when writing his Epistle to the Hebrews, at the 10th chapter and 22nd verse. "Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water."
Leviticus 1:9 ; 8:21 Hebrews 10:22
