Whitewash

hwit’wosh: the American Revised Version margin gives "whitewash" for "untempered mortar" in Eze 13:10 and 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.
