Then followed the ninth plague. For several days all of Egypt was enveloped in a thick and impenetrable veil of darkness which extinguished all lights kindled. The Egyptians were gripped with fear, and remained glued to their places wherever they stood or sat.

Only in Goshen, where the children of Israel dwelt, there was light. But not all of the Jews were saved from this plague. There were a few who wanted to be regarded as Egyptians rather than as members of the Hebrew race, and who tried, therefore, to imitate the Egyptians in everything, or, as we call it, to assimilate themselves. They did not want to leave Egypt. These people died during the days of darkness.

Again Pharaoh tried to bargain with Moses and Aaron, bidding them depart with all their people, leaving their flocks and herds behind as a pledge. Moses and Aaron informed him, however, that they would accept nothing less than complete freedom for the men, women, and children, and that they were to take all their belongings with them.

Now Pharaoh became angry and ordered Moses and Aaron to leave and never to return. He warned them that if they were to come before him again they would die. Moses replied that it would not be necessary for them to see Pharaoh, for G-d would send one more plague over Egypt, after which Pharaoh would give his unconditional permission for the children of Israel to leave Egypt.

Exactly at midnight, Moses continued, G-d would pass over Egypt and smite all firstborn, man and beast. Of the children of Israel, however, nobody was to die. A bitter cry would sweep Egypt, and all the Egyptians would be gripped with terror, lest they all die. Then Pharaoh himself would come to seek out the leaders of the Hebrews, and beg them to leave Egypt without delay!

With these words, Moses and Aaron left Pharaoh, who was seething with rage.
