Israel has encountered God in his holiness, power and grace (Exodus 19). God has given Israel laws to live by — first the ten commandments (chapter 20) as the foundation, then three chapters of practical examples of what keeping this law might mean in practice. Now the Covenant must be confirmed in a sacred ceremony. The ceremony includes the sprinkling of sacrificial blood and the extraordinary privilege of a meal with God. All foreshadowing yet again another sacred meal by which followers of Jesus will commune forever with him.
