The act of swearing by the name of God was wont to be symbolized by the offering of sacrifice. It has been shown that the number _seven_ was an emblem of the oath. One of the things, therefore, denoted by the offering of seven sacrifices was the swearing of it. Once, and again and again, did Balak at Balaam's suggestion build seven altars, and offer a bullock and a ram on every altar.[148] And whether we believe the religious homage presented on each occasion to have been in ignorance addressed to the true God, or to some idol, there is reason to conclude that the injunction of the false prophet was suggested by the practice of the people of God, and that the service was an emblematical representation of the religious worship offered in the swearing of the oath. Besides, was not his design to curse Israel either by the true God, or by some gods of the heathen? And was it not in imitation of some such practices, as that which he attempted, that Goliath cursed David by his gods? But offerings of this kind were presented when federal transactions were ratified by the worshippers of God. After the three friends of Job had uttered all their hard speeches against him, the Lord addressed to them a command which included not less than the injunction, to enter into an amicable compact with the afflicted character whom they had so much misrepresented, and also to accompany it with a religious service.[149] The duty enjoined embodied likewise a confession of sin and an appeal to God for the truth of their acknowledgments. The covenant promise made to them was, that God would accept them through the intercession of Job,--not as if that were of itself meritorious, but approved through the great Mediator. The offering of seven bullocks and seven rams was a confirmation of their friendly Covenant, and could not be less than an emblem of their oath to the Most High. Finally. In the first year of his reign, Hezekiah declared, "Now it is in mine heart to make a Covenant with the Lord God of Israel, that his fierce wrath may turn away from us." That He, the priests and Levites, the rulers of Jerusalem, and as many of the congregation of Israel as were present, carried his design into effect, for the first time, on the occasion of the solemnities which took place in the first month, appears from his command, uttered when he declared his devout intention. He said,--"My sons, be not now negligent: for the Lord hath chosen you to stand before him, to serve him, and that ye should minister unto him and burn incense (or, _offer sacrifice_)."[150] That all Judah and Israel were enjoined to accede to the Covenant, in the second month, is manifest from the King's command to them--"Now be ye not stiff-necked, as your fathers were, but yield yourselves unto the Lord, and enter into his sanctuary, which he hath sanctified for ever; and serve the Lord your God, that the fierceness of his wrath may turn away from you."[151] That such of them
