על חיי משה, ספר א ל״בOn the Life of Moses, Book I 32

א׳
1[176] Such was his prediction. But at sunset a south wind of tremendous violence arose, and, as it rushed down, the sea under it was driven back, and, though regularly tidal, was on this occasion more so than usually, and swept as into a chasm or whirlpool, when driven against the shore. No star appeared, but a thick black cloud covered the whole heaven, and the murkiness of the night struck terror into the pursuers. Moses now, at God’s command,
ב׳
2[177] smote the sea with his staff, and as he did so it broke and parted into two. Of the waters thus divided, one part rose up to a vast height, where the break was made, and stood quite firmly, motionless and still like a wall; those behind were held back and bridled in their forward course, and reared as though pulled back by invisible reins; while the intervening part, which was the scene of the breaking, dried up and became a broad highway. Moses, seeing this, marvelled and was glad, and in the fullness of his joy encouraged his men and bade them move on with all speed.
ג׳
3[178] And, when they were about to begin the passage, a most extraordinary sign occurred. The guiding cloud, which at other times stood in front, turned round to the back of the multitude to form its rearguard, and thus posted between the pursuers and pursued regulated the course of the latter and drove them before it under safe protection, but checked and repelled the former when they strove to advance. When the Egyptians saw this, tumult and confusion prevailed everywhere among them. In their terror their ranks fell into disorder. They tumbled over each other, and sought to escape, but it was of no avail; for,
ד׳
4[179] while the Hebrews with their women and children, still mere infants, crossed on a dry road in the early dawn, it was otherwise with the Egyptians. Under the north wind the returning tide was swept back, and hurled its lofty billows upon them. The two sections of the sea rolled upon them from either side, united and submerged them, horses, chariots and all, with not even a torchbearer  left to announce to the people of Egypt the sudden disaster.
ה׳
5[180] This great and marvellous work struck the Hebrews with amazement, and, finding themselves unexpectedly victorious in a bloodless conflict, and seeing their enemies, one and all, destroyed in a moment, they set up two choirs, one of men and one of women, on the beach, and sang hymns of thanksgiving to God. Over these choirs Moses and his sister presided, and led the hymns, the former for the men and the latter for the women.
