ISB ~ John 6 v4

the Passover:Three times this feast is mentioned in John (2:13; 11:55). It was celebrated annually in Jerusalem to commemorate Israel’s deliverance from Egyptian slavery (Ex 12). Central to the feast is a liturgical meal, called a seder, in which the story of the Exodus is retold, psalms are sung, and a lamb is eaten with unleavened bread and other condiments. The evangelist mentions this upcoming feast to hint that Jesus will give new and greater meaning to the Passover. He is the true “Lamb of God” (1:29), whose redeeming work will accomplish a new deliverance from the slavery of sin (8:31-36) in a sacramental and liturgical meal (6:53-58; 1 Cor 5:7-8). The significance of Passover, here placed in the background of John 6, will move to the foreground when Jesus transforms this feast into the memorial meal of the New Covenant at the Last Supper (Mt 26:17-29; CCC 1340). See note on Jn 19:36.
