Throughout the Scriptures infinite care is taken to preclude every notion that the Most High God can be represented in visible form. He manifested Himself at Sinai to the children of Israel, but though the mount burned with fire, and there were clouds and thick darkness, and the voice of a trumpet speaking long and loud, the people were reminded with the utmost solemnity that "they saw no manner of similitude."[685] Indeed, in later times, when there was a keener jealousy of every anthropomorphic expression, the giving of the law is rather represented as a part of the ministry of angels. The word _Makom_, or "Place," is substituted for Jehovah, so that Moses and the elders and the Israelites do not see God but only His _Makom_, the space which He fills;[686] the delivery of the law is ascribed to angelic ministers. At times the angels are almost identified with the careering flames and rushing winds which a modern theologian describes to us as being "the skirts of their garments, the waving of their robes"; for is it not written, "He that maketh the winds His angels and the flaming fires His ministers"?[687] And in the daring description of Jehovah's visible manifestation of Himself to Moses, when He hid him in that fissure of the rock with the hollow of His hand, Moses only observes as it were the fringe and evanishment of His glory, "dark with excessive light." It was natural that Jehovah should reveal Himself to Elijah under the aspect of those awful elemental forces with which his solitary life had made him familiar. No spot in the world is more suitable for those powers in all their fire and magnificence than the knot of mountains which crowd the Sinaitic peninsula with their entangled cliffs. Travellers have borne witness to the overwhelming violence and majesty of the storms which rush and reverberate through the granite gorges of those everlasting hills. It was in such surroundings that Jehovah spoke to the heart of his servant.
