the dense, dark storm-cloud in which God draws near, present yet hidden from sight
This is not ordinary weather and not plain darkness. It is a specific thing: a heavy, black storm-cloud, and in the Bible it belongs to God alone. The word is never used for a passing rain cloud or a dark night. Every one of its fifteen appearances stands in a scene where God is coming near, whether to save or to judge.
Its single most striking feature is a paradox. The cloud is thick enough to hide God completely, so that no one can see a form or shape inside it. Yet that same cloud is exactly where God has chosen to be. It reveals him by concealing him. At Mount Sinai the people shrink back from it, while Moses walks straight into it, because God is there. Centuries later Solomon says the same God has come to live in this cloud inside the temple.
The word is close to two others without being the same as either. It is heavier and darker than the ordinary word for a עָנָן, the everyday cloud that guided Israel through the wilderness. And it is more physical than the word for חֹשֶׁךְ, which is simply the absence of light. This cloud is a solid mass you could walk toward, and its darkness comes from how dense it is.
The senses below follow the same cloud through the different scenes where it appears:
- the cloud where God dwells, present but unseen, at Sinai and in the temple
- the storm-cloud beneath his feet as he sweeps down in power
- the black cloud of the day of the LORD, when his coming means judgment
- the cloud wrapped around the newborn sea, holding the waters in at creation
Nuances
Disputed
Whether the basic meaning of the word is "dense, dark storm-cloud" (with darkness a derived nuance of the cloud's density) or an irreducible compound "cloud-darkness" that cannot be reduced to either pole.
- majorityThe base concept is a dark storm- or rain-cloud, with "gloom" a secondary nuance that grew dominant in Biblical Hebrew because of the word's exclusively theophanic use; this is backed by the Ugaritic ʿrpt and Akkadian erpetu cognates.; BDB, p. 791, s.v. עֲרָפֶל; HALOT, s.v. עֲרָפֶל; H. Niehr, "עֲרָפֶל," Theological Dictionary of the Old Testament, vol. XI, pp. 371-376
- minorityThe word is a distinctive sky-phenomenon best described as a compound "cloud-darkness" that resists reduction to either "cloud" or "darkness" alone; some reference works decline to give either pole priority.; Chaim Cohen, "The Basic Meaning of the Term ʿarāpel," Hebrew Studies 36 (1995): 7-12; David J.
