ISB ~ John 13 v1

feast of the Passover:The original meaning of this feast, celebrating the passing of the angel of death over the Israelites and their escape from Egypt (Ex 12:13), is being reshaped by the works and words of Christ, who will “pass over” to the Father through the upcoming events of his Passion, Resurrection, and Ascension. This saving work of Jesus will inaugurate a new Exodus, liberating the human family from sin, selfishness, and Satan (1:29; 8:34-36) (CCC 1340). See note on Jn 6:4.

to the end:i.e., “completely” or “to the fullest extent” (CCC 609).
