Context10:21 1 The Lord said to Moses, “Extend your hand toward heaven 2 so that there may be 3 darkness over the land of Egypt, a darkness so thick it can be felt.” 4
10:22 So Moses extended his hand toward heaven, and there was absolute darkness 5 throughout the land of Egypt for three days. 6
1 sn The ninth plague is that darkness fell on all the land – except on Israel. This plague is comparable to the silence in heaven, just prior to the last and terrible plague (Rev 8:1). Here Yahweh is attacking a core Egyptian religious belief as well as portraying what lay before the Egyptians. Throughout the Bible darkness is the symbol of evil, chaos, and judgment. Blindness is one of its manifestations (see Deut 28:27-29). But the plague here is not blindness, or even spiritual blindness, but an awesome darkness from outside (see Joel 2:2; Zeph 1:15). It is particularly significant in that Egypt’s high god was the Sun God. Lord Sun was now being shut down by Lord Yahweh. If Egypt would not let Israel go to worship their God, then Egypt’s god would be darkness. The structure is familiar: the plague, now unannounced (21-23), and then the confrontation with Pharaoh (24-27).
2 tn Or “the sky” (also in the following verse). The Hebrew term שָׁמַיִם (shamayim) may be translated “heavens” or “sky” depending on the context.
3 sn The verb form is the jussive with the sequential vav – וִיהִי חֹשֶׁךְ (vihi khoshekh). B. Jacob (Exodus, 286) notes this as the only instance where Scripture says, “Let there be darkness” (although it is subordinated as a purpose clause; cf. Gen 1:3). Isa 45:7 alluded to this by saying, “who created light and darkness.”
4 tn The Hebrew term מוּשׁ (mush) means “to feel.” The literal rendering would be “so that one may feel darkness.” The image portrays an oppressive darkness; it was sufficiently thick to possess the appearance of substance, although it was just air (B. Jacob, Exodus, 286).
5 tn The construction is a variation of the superlative genitive: a substantive in the construct state is connected to a noun with the same meaning (see GKC 431 §133.i).
6 sn S. R. Driver says, “The darkness was no doubt occasioned really by a sand-storm, produced by the hot electrical wind…which blows in intermittently…” (Exodus, 82, 83). This is another application of the antisupernatural approach to these texts. The text, however, is probably describing something that was not a seasonal wind, or Pharaoh would not have been intimidated. If it coincided with that season, then what is described here is so different and so powerful that the Egyptians would have known the difference easily. Pharaoh here would have had to have been impressed that this was something very abnormal, and that his god was powerless. Besides, there was light in all the dwellings of the Israelites.
