Whitewash hwit'wosh: the American Revised Version margin gives "whitewash" for "untempered mortar" in Ezekiel 13:10; and Ezekiel 22:28. `Her prophets have daubed for them,' i.e. seconded them, "with whitewash," thus giving "a slight wall" (13:10 margin) a specious appearance of strength.
See MORTAR, UNTEMPERED.
