Exodus, Chapter twelve of the Hebrew Scriptures, beautifully depicts the sacrificial lamb of God, Jesus Christ, for the sins of all. Let us behold our Saviour Jesus as the Paschal Lamb on which we feed this Passover season. Approximately four days prior to his crucifixion, Jesus Christ rode in triumph through the streets of Jerusalem, on an ass,and up to the temple, that all might see him as the Messiah, Judah's lamb, chosen of God and ordained from the foundation of the world.
You will read in Deuteronomy Chapter sixteen that God no longer allowed the Israelites to slay the Lamb in their own houses, but appointed a place for its celebration. In the wilderness, the Israelites brought their offerings to the tabernacle where the lamb was slaughtered; but at its first appointment, in Egypt. Afterward, as it is written in verse five "Thou mayest not sacrifice the Passover lamb within any of thy gates, which the Lord thy God giveth thee; but at the place which the Lord they God shall chose to place his name in, there thou shalt sacrifice the Passover at even at the going down of the sun, at the season that thou camest forth out of Egypt."
Jerusalem is the place chosen by God for God's temple was there and salvation is of the Jews, Jesus Christ himself a Jew, as it is written. John 4:22. Jacob, when he encountered the site where the temple was to stand centuries later, said of Jerusalem: "And he was afraid, and said, How dreadful is this place! this is none other but the house of God, and this is the gate of heaven." Genesis 28:17.
Purge out there the old leaven, that ye may be a new lump, as ye are unleavened, For even Christ our passover is sacrificed for us;
Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. 1 Corinthians 5:7-8
