he kept the Passover: See Exodus 12:1–27. The first Passover (Exodus 12:28–30) started the Exodus (Exodus 12:31–42, 50–51) and began the yearly Passover celebration as a remembrance (Exodus 12:43–49; 13:1–16).
the sprinkling of blood: Sprinkling the blood of sacrifices in the old covenant was similar to the sprinkling of Christ’s blood (see Hebrews 9:12–14, 18–22).
