Exodus 12:27

The passover was both a sacrifice, as it was offered to God, as it appears from Exodus 23:18, Exodus 34:25 Numbers 9:7,13 Deu 16:2,5; and because there was in it the shedding and sprinkling of blood, wherein the essence of a sacrifice consists, 2 Chronicles 30:16, 2 Chronicles 35:11,13; and also a sacrament, as it was received and eaten by men. The people bowed the head, in token of their thankful acknowledgment of God's favours, and of their cheerful submission to God's command and ordinance. See 2 Chronicles 29:30.
