And Moses stretch forth his hand towards heaven: and there came horrible darkness in all the land of Egypt for three days.

And Moses stretched out his hand toward the heavens; and there was a thick darkness throughout the land of Egypt three days:

And Moses stretched forth his hand towards heaven: and there was a thick darkness in all the land of Egypt three days:

And Moses stretcheth out his hand towards the heavens, and there is darkness, thick darkness in all the land of Egypt three days;

And when Moses' hand was stretched out, dark night came over all the land of Egypt for three days;

And Moses extended his hand into the sky. And there came a horrible darkness in the entire land of Egypt for three days.

Et extendit Moses manum suam in coelum: et fuerunt tenebrae caliginosae in tota terra Aegypti tribus diebus.

And Moses stretched forth his hand. By this darkness God not only wished to reprove the blindness of Pharaoh's mind, but in every way to convince him how senseless and mad he was in his resistance. There is no blessing which is more common to all men, from the very highest even to the lowest, than light, which is enjoyed not less by the humblest and most contemptible people than by the greatest kings. It was, then, a terrible judgment of God, that the whole world should be enlightened by the sun's rays, whilst the Egyptians, although possessing sight, were plunged in darkness. What madness, then, could be greater than theirs, when in their hardness of heart they cease not to contend against God's hand, formidable as it was? Their waters turned into blood had denied them drink; frogs and other animals had filled the whole country; they had almost been consumed by lice; their limbs had been enfevered by boils; the hail had destroyed part of their corn; the locusts had brought still increased destruction; even rocks and stones should have been somewhat terrified by such warnings. This admonition, then, was very seasonable, viz., that darkness should be spread over all Egypt, that they might understand that, when God was wrath with them, the very hosts of heaven were armed against them. And, in order that God's vengeance should be neither obscure nor doubtful, the cause of the darkness could not be assigned to an eclipse, both on account of its density and the time it lasted; for both of these circumstances are expressly noted by Moses, that it may be more clear that the sun was obscured to the Egyptians, because they had endeavored to extinguish God's glory by their impious contempt. On the contrary, the Israelites must have acquired new cheerfulness when they recognized in the sun's brightness that God's paternal countenance was shining upon them; for He then enlightened them with His favor, as if to show them the freedom of their egress. And, indeed, He might have at once led them forth from their astonished enemies; but He chose, as we shall see, to prepare their departure in another way.

And Moses stretched forth his hand toward heaven, and there was a thick darkness over all the land of Egypt three days. The eleventh, twelveth, and thirteenth days of the month Abib; with this compare the fifth vial, Revelation 16:10.
