Isaiah 1:19 If ye be willing and obedient, ye shall eat the good of the land: 20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it.
[Patriarchs & Prophets pp 311>312] Upon descending from the mountain, “Moses came and told the people all the words of the Lord, and all the judgments: and all the people answered with one voice, and said, All the words which the Lord hath said will we do.” This pledge, together with the words of the Lord which it bound them to obey, was written by Moses in a book. Then followed the ratification of the covenant. An altar was built at the foot of the mountain, and beside it twelve pillars were set up, “according to the twelve tribes of Israel,” as a testimony to their acceptance of the covenant.
Sacrifices were then presented by young men chosen for the service. Having sprinkled the altar with the blood of the offerings, Moses “took the book of the covenant, and read in the audience of the people.” Thus the conditions of the covenant were solemnly repeated, and all were at liberty to choose whether or not they would comply with them. They had at the first promised to obey the voice of God; but they had since heard His law proclaimed; and its principles had been particularized, that they might know how much this covenant involved.
Again the people answered with one accord, “All that the Lord hath said will we do, and be obedient.” “When Moses had spoken every precept to all the people according to the law, he took the blood, ... and sprinkled both the book and all the people, saying, This is the blood of the testament which God hath enjoined unto you.” Hebrews 9:19, 20.
Exodus 24:4 And Moses wrote all the words of the Lord, and rose up early in the morning, and builded an altar under the hill, and twelve pillars, according to the twelve tribes of Israel. 5 And he sent young men of the children of Israel, which offered burnt offerings, and sacrificed peace offerings of oxen unto the Lord.
May God add His blessing to the study of His word. “Good night” and God bless!
