The young Moses, however, grew in favour with the king, who laid upon him the great office of introducing illustrious foreigners to the royal presence. But Moses kept ever before his eyes the aim of his life, to relieve his people from their intolerable burdens. One day he presented himself before the king and said, “Sire! I have a petition to make of thee.” Pharaoh answered, “Say on, my son.” Then said Moses, “O king! every labourer is given one day in seven for rest, otherwise his work becomes languid and unprofitable. But the children of Israel are given no day of rest, but they work from the first day of the week to the last day, without cessation; therefore is their work inferior, and it is not executed with that heartiness which might be found, were they given one day in which to recruit their strength.” Pharaoh said, “Which day shall be given to them?” Moses said, “Suffer them to rest on the seventh day.” The king consented, and the people were given the Sabbath, on which they ceased from their labours; therefore they rejoiced greatly, and for a thousand years the last day of the week was called “The gift of Moses.”[476] As the command to destroy all the male children had been withdrawn the day that Moses was cast into the Nile, the people had multiplied greatly, and again the fears of the Egyptians were aroused. Therefore the king published a new decree, with the object of impeding the increase of the bondsmen. He required the Egyptian task-masters to impose a tale of bricks on every man, and if at evening the tale of bricks was not made up, then, in place of the deficient bricks, even though only one brick was short, they were to take the children of those who had not made up their tale, and to build them into the wall in place of bricks.[477] Thus upon one misery another was piled. In order that this decree might be executed with greater certainty, ten labourers were placed under one Hebrew overseer, and one Egyptian task-master controlled the ten overseers. The duty of the Hebrew overseers was to wake the ten men they were set over, every morning before dawn, and bring them to their work. If the Egyptian task-masters observed that one of the labourers was not at his post, he went to the overseer, and bade him produce the man immediately.
