What was the original blood covenant?
The word Testament means covenant. The Old Testament describes the old covenant God made. The New Testament describes the new covenant Gad made with humans through Christ Jesus. The Old Testament looks forward to Christ where as the New Testament looks back at the promises of Christ.
God made many covenants in the Old Testament, but I assume you are speaking about the "New Covenant" vs the "Old Covenant" which God gave Israel through Moses at Mount Sinai. The "New Covenant" or second was mentioned in the Old Testament several times as a covenant which was yet future. The "New Covenant" started in the New Testament when Jesus Christ died on the cross of Calvary, was buried, and was resurrected the third day. The 'Old Covenant" was by Law and the "New Covenant" was by grace.
It's a form of binding agreement and solemn undertaking.
An agreement that brings about a relationship of commitment between God and his people.

In Christianity, there are several covenants that God made with humanity throughout the Bible. Some of the most notable covenants include the covenant with Noah (Genesis 9), the covenant with Abraham (Genesis 12), the covenant with Moses (Exodus 19), and the new covenant through Jesus Christ (Luke 22). Each covenant established a particular relationship between God and his people.

You could use the word "covenant" The Old Testament was the old covenant concerning the law and the New Testament is the new covenant which explains the Grace of God to mankind in sending His only begotten Son into the world to save sinners. The old covenant is no longer in force. Jesus Christ is the way, the truth, and the life. No one comes to the Father but through Him (Jesus Christ)
