The answer is: Sprinkled it on the people

Ex 24:7-8

Moses had a huge responsibility – he was more than just the leader of a nation; he was the mediator between the Israelites and the Divine. When he received the Book of the Covenant, it outlined laws and promises that would guide the people. After reading it aloud, he took a dramatic step by sprinkling blood on the people, which symbolized the sealing of this covenant.

This act of blood sprinkling was more than a mere ritual; it was a bold gesture that bound the people to their commitment to obey the laws. Blood in ancient cultures often represented life and atonement. For the Israelites, this vivid illustration was a profound reminder that they were entering into a serious agreement with their Creator—a promise sealed in life-giving substance.

Interestingly, this practice echoes throughout biblical texts. For instance, in the New Testament, when Jesus speaks of the "new covenant" at the Last Supper, He refers back to these ancient traditions. The symbolic use of wine as His blood links to that sprinkling, revitalizing the themes of sacrifice and commitment to divine principles.

The covenant with Moses served as a foundation for later Judaic laws and societal structure. Beyond the sprinkle of blood and other rituals, it ultimately invited the people into a relationship of responsibility and hope, emphasizing divine guidance in the wilderness of life. It's both a remarkable spiritual leap and a sobriety check for anyone journeying alongside these ancient texts.
