19:5 And now, if you will diligently listen to me and keep my covenant, then you will be my special possession out of all the nations, for all the earth is mine, 19:6 and you will be to me a kingdom of priests and a holy nation.’ These are the words that you will speak to the Israelites.”

19:7 So Moses came and summoned the elders of Israel. He set before them all these words that the Lord had commanded him, 19:8 and all the people answered together, “All that the Lord has commanded we will do!” So Moses brought the words of the people back to the Lord.

8:7 For if that first covenant had been faultless, no one would have looked for a second one. 8:8 But showing its fault, God says to them,

8:9 “It will not be like the covenant that I made with their fathers, on the day when I took them by the hand to lead them out of Egypt, because they did not continue in my covenant and I had no regard for them, says the Lord.

Hebrews 9:19-23

9:19 For when Moses had spoken every command to all the people according to the law, he took the blood of calves and goats with water and scarlet wool and hyssop and sprinkled both the book itself and all the people, 9:20 and said, “This is the blood of the covenant that God has commanded you to keep.” 9:21 And both the tabernacle and all the utensils of worship he likewise sprinkled with blood. 9:22 Indeed according to the law almost everything was purified with blood, and without the shedding of blood there is no forgiveness. 9:23 So it was necessary for the sketches of the things in heaven to be purified with these sacrifices, but the heavenly things themselves required better sacrifices than these.
