1 Kings 18:44

Verse 1 Kings 18:44. There ariseth a little cloud out of the sea, like a man's hand.] איש ככף kechaph ish, like the hollow of a man's hand. In the form of the hand bent, the concave side downmost. I have witnessed a resemblance of this kind at sea previously to a violent storm, a little cloud the size of a man's hand first appearing, and this increasing in size and density every moment, till at last it covered the whole heavens, and then burst forth with incredible fury.

Mr. Bruce mentions a similar appearance in Abyssinia: - "Every morning, in Abyssinia, is clear, and the sun shines. About nine a small cloud, not above four hundred feet broad, appears in the east, whirling violently round, as if upon an axis; but arrived near the zenith, it first abates its motion, then loses its form, and extends itself greatly, and seems to call up vapours from all opposite quarters. These clouds, having attained nearly the same height, rush against each other with great violence, and put me always in mind of Elijah foretelling rain on Mount Carmel." - Travels, vol. v., page 336, edit. 1806.
