(Heb. kerah, from its smoothness) Job 37:10 (R.V., "ice"); Gen. 31:40; Jer. 36:30; rendered "ice" in Job 6:16, 38:29; and "crystal" in Ezek. 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 Ps. 78:47 the word rendered "frost" (R.V. 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.
