(Heb. kerah, from its smoothness) Job 37:10 (RSV, "ice"); Genesis 31:40 ; Jeremiah 36:30 ; rendered "ice" in Job 6:16 Job 38:29 ; and "crystal" in Ezekiel 1:22 . "At the present day frost is entirely unknown in the lower portions of the valley of the Jordan, but slight frosts are sometimes felt on the sea-coast and near Lebanon." Throughout Western Asia cold frosty nights are frequently succeeded by warm days.
In Psalms 78:47 the word rendered "frost" (RSV marg., "great hail-stones"), hanamal , occurs only there. It is rendered by Gesenius, the Hebrew lexicographer, "ant," and so also by others, but the usual interpretation derived from the ancient versions may be maintained.
