It was Ahab’s house that was asking for peace, but they were asking for physical peace, not God’s peace. God does not like the world’s definition of peace, which is, “Leave me alone! I enjoy my miserable life.” When someone is at war with God and they are about to see God’s sword coming down on them, they will ask for “peace.” But in this account, they were lying.
Two key themes in this passage are the arrival of Yeshua into Yerushalayim on a donkey and the responsive public cry, “Blessed is He who comes in the name of the Lord.” That blessed One came as the Lamb of God, yet Israel’s “shepherds” ignored Him, searching for the prophesied Lion of Yehudah. When the Lamb of God returns as the Lion of Yehudah, no one will be able to ignore Him.
Once in a while it’s good to get back to basics. The “gospel” of the Kingdom of God is more than the life, death and resurrection of the Messiah. Shimini Atzeret, or the Eighth Day (Isaiah 52), is a celebration of salvation, peace, restoration and the reign of God.
