Out of the peculiar relation in which Israel stood from all antiquity to his God, out of the protection and prosperity which he had granted to the patriarchs and their seed, out of the liberation from the oppression of the Egyptians, which Jehovah had prepared for the Israelites with a strong arm, out of the bestowal of Canaan, _i.e._ the promise of Jehovah to conquer the land, which the Israelites had now possessed for centuries, there grew up in the circles of the priests, from about the time of Samuel, the idea of the covenant which Jehovah had made with the patriarchs, and through them with Israel. Jehovah had assured Israel of his protection and blessing; on the other hand, Israel had undertaken to serve him, to obey his commands, and do his will. If Israel lives according to the command of Jehovah, the blessing of his God will certainly be his in the future also; the reward of true service will not and cannot be withheld from him. The will of Jehovah which Israel has to obey, the law of Jehovah which he has to fulfil, was contained in the moral precepts, the rules of law, and rubrics for purification and sacrifice, the writing down of which in the frame-work of a brief account of the fortunes of the fathers, the slavery in Egypt, the liberation and the conquest of Canaan, on the basis of older sketches of separate parts, was brought to a conclusion at Hebron, in the priestly families of the tribe of Aaron, about the first decade of David's reign (I. 385). In this writing were laid down the views held by the priesthood on the life pleasing to God, on the past of the nation and the priests, and of the correct mode of worship. It was the ideal picture of conduct in morals, law and worship which the priests strove after, which must in any case have existed in that great period when Jehovah spoke to the Israelites by the mouth of Moses. And, as a fact, the foundations of the moral law, the fundamental rules of law and customs of sacrifice, as we found above (I. 484), do go back to that time of powerful movement of the national feeling, of lofty exaltation of religious emotion against the dreary polytheism of Egypt.
