The LORD our God made a covenant with us in Horeb.
Deuteronomy 4:23
Take heed unto yourselves, lest ye forget the covenant of the LORD your God, which he made with you, and make you a graven image, or the likeness of any thing, which the LORD thy God hath forbidden thee.
Exodus 19:5-8
5
Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine:
6
And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.
7
And Moses came and called for the elders of the people, and laid before their faces all these words which the LORD commanded him.
8
And all the people answered together, and said, All that the LORD hath spoken we will do. And Moses returned the words of the people unto the LORD.
Exodus 24:8
And Moses took the blood, and sprinkled it on the people, and said, Behold the blood of the covenant, which the LORD hath made with you concerning all these words.
Hebrews 8:6-13
6
But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
7
For if that first covenant had been faultless, then should no place have been sought for the second.
8
For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
9
Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
10
For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
11
And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
12
For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
13
In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Hebrews 9:19-23
19
For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and sprinkled both the book, and all the people,
20
Saying, This is the blood of the testament which God hath enjoined unto you.
21
Moreover he sprinkled with blood both the tabernacle, and all the vessels of the ministry.
22
And almost all things are by the law purged with blood; and without shedding of blood is no remission.
23
It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
