It is supposed that at this time Moses came to the relief of Israel, and asked permission for his people to withdraw a few days into the desert to offer sacrifices to their God. This was the occasion for the king both to deny the request and to double the tasks meted out to the brickmakers by withholding straw and requiring the same amount of work to be accomplished as before. Then, according to the Hebrew version, grievous plagues were sent upon Egypt, and only when the king's son, with the other first born, was stricken in the night, did the monarch concede to the entreaties of his own people and bid the Hebrews depart from his land. The story is familiar to all--how when he came to think of the six hundred thousand valued bonds-people of which he was now bereft, he dispatched the flower of Egyptian charioteers to prevent the Hebrews crossing the Red Sea and bring them back to do his bidding. To these despairing people to whom light seemed about to dawn, the fact that they were able to cross over while the Egyptian horses were ensnared and drowned, seemed a miracle enacted for their deliverance. It has since been noted that similar tidal action at this point has sometimes repeated itself. To the Hebrews, believing firmly in the inspired mission of Moses, it was regarded later as an example of how for the dutiful "all things work together for good." TWENTIETH DYNASTY.[4] Ramses III. was the first important ruler of the Twentieth dynasty. He and his immediate successors were able to hold intact the vast empire won by earlier kings. We hear no more of aggressive wars for conquest. However, the time had come when Egypt did well when she maintained such territories as belonged to her. Men of Crete, other islanders and sea-faring people, made common cause against the Asiatic shore early in this reign. Ramses watched their progress until they attacked the Egyptian province of Palestine. Not willing to lose this, the pharaoh marched against the plundering bands and utterly routed them, taking many captives. Three other campaigns were directed by this king, but they were carried on to defend Egyptian borders and hold together tributary provinces. Like his father, Ramses III. was a builder. Like him, too, he appropriated earlier temples and monuments for his own fame and glory. He built a fleet on the Red Sea, continued the profitable commercial intercourse with Punt, and caused a large reservoir to be constructed in Palestine. Another thing he did, which all histories have been careful to chronicle: he ordered trees and shrubs to be systematically planted throughout the realm. In a land where for months together the sun pours its hot rays down on a defenseless people, he tried to bring rest and cooling shade where both were sorely needed.
