For if that first covenant had been faultless, then no place would have been sought for a second. Because finding fault with them, He says: "Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah— 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 did not continue in My covenant, and I disregarded them, says the LORD. For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. None of them shall teach his neighbor, and none his brother, saying, "Know the LORD," for all shall know Me, from the least of them to the greatest of them. For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more." In that He says, "A new covenant, " He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine. And you shall be to Me a kingdom of priests and a holy nation.' These are the words which you shall speak to the children of Israel.' So Moses came and called for the elders of the people, and laid before them all these words which the LORD commanded him. Then all the people answered together and said, "All that the LORD has spoken we will do." So Moses brought back the words of the people to the LORD.
Then he took the Book of the Covenant and read in the hearing of the people. And they said, “All that the LORD has said we will do, and be obedient.” And Moses took the blood, sprinkled it on the people, and said, “This is the blood of the covenant which the LORD has made with you according to all these words.”
'When I passed by you again and looked upon you, indeed your time was the time of love; so I spread My wing over you and covered your nakedness. Yes, I swore an oath to you and entered into a covenant with you, and you became Mine,' says the Lord GOD.
And behold, the word of the LORD came to him, saying, “This one shall not be your heir, but one who will come from your own body shall be your heir.”
When Abram was ninety-nine years old, the LORD appeared to Abram and said to him, 'I am Almighty God; walk before Me and be blameless. And I will make My covenant between Me and you, and will multiply you exceedingly.” Then Abram fell on his face, and God talked with him, saying: 'As for Me, behold, My covenant is with you, and you shall be a father of many nations.
I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you.
Also I give to you and your descendants after you the land in which you are a stranger, all the land of Canaan, as an everlasting possession; and I will be their God."
Then I saw that for all the causes for which backsliding Israel had committed adultery, I had put her away and given her a certificate of divorce; yet her treacherous sister Judah did not fear, but went and played the harlot also.
“Return, O backsliding children,” says the LORD; “for I am married to you. I will take you, one from a city and two from a family, and I will bring you to Zion.
"Behold, the days are coming, says the LORD
Then He gave him the covenant of circumcision; and so Abraham begot Isaac and circumcised him on the eighth day; and Isaac begot Jacob, and Jacob begot the twelve patriarchs.
In the same manner He also took the cup after supper, saying, "This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me."
Brethren, I speak in the manner of men: Though it is only a man's covenant, yet if it is confirmed, no one annuls or adds to it. Now to Abraham and his Seed were the promises made. He does not say, "And to seeds," as of many, but as of one, "And to your Seed,"who is Christ. And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect.
Therefore remember that you, once Gentiles in the flesh—who are called Uncircumcision by what is called the Circumcision made in the flesh by hands— that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world.
Let us be glad and rejoice and give Him glory, for the marriage of the Lamb has come, and His wife has made herself ready."
