The children of Jacob sojourned in the land of Ham four hundred years. When Jehovah called his people out of Egypt they were fitted to receive the laws and institutions which he designed to give them, and to take the high position he assigned them among the nations of the earth. And lest, during their long sojourn in the wilderness, they should lose the arts of civilized life, they were employed in the construction of the tabernacle. By the minute enumeration of all that was required for the completion of this work, we see that the erection involved an extensive acquaintance with the mechanical arts, and of those, too, which indicate a high degree of advancement in the luxuries of polished life. Thus the generation born in the wilderness were instructed, and preserved from degenerating into mere shepherds, hunters, or warriors. The restless were occupied, and the work proved a bond of union for the whole people, exciting the interest and employing the energies of all the different classes of the great multitude. The long ages of the sojourn of the children of Jacob were drawing to a close. The iniquity of the Canaanites was now full; the children of Israel were prepared to be numbered among the nations of the earth; and the events dictated by the craft and policy of men were ordained to promote the infinite designs of Jehovah. For four hundred years the descendants of Jacob had dwelt in Goshen. From a pastoral they were already become an agricultural people; they had learned to prize the comforts of an established life, of quiet, peaceful homes, of pleasant places of abode. Dwelling in the richest portion of Egypt, protected from all foreign aggression, they there enjoyed abundance, peace, and prosperity, to which their wanderings in the desert furnished a sad contrast. The policy of Egypt had excluded the Israelites from her crimes. The energy, the love of change and adventure, which a martial life imparts, were unfelt; and had not oppression driven the Israelites from Egypt, the promise of that goodly land destined for their race had hardly induced the nation to leave their present abundance and protection. Thus, by the various dispensations of his providence, Jehovah was at once preparing a guide, leader, ruler, and future lawgiver for his people, while by the continued vexation, oppression, and cruelty of the Egyptian rulers, he was suffering them to alienate the affections of the children of Jacob from a country which had become the native land of the Israelites, which was the birth-place of generation after generation.
