(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.
"Hoar frost" (Heb. kephor, so called from its covering the
ground) is mentioned in Ex. 16:14; Job 38:29; Ps. 147:16.
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.
