The roast lamb dinner that many eat on Easter Sunday goes back earlier than Easter to the first Passover of the Jewish people. The sacrificial lambwas roasted and eaten, together with unleavened bread and bitter herbs in hopes that the angel of God would pass over their homes and bring no harm. As Hebrews converted to Christianity, they naturally brought along their traditions with them. The Christians often refer to Jesus as The Lamb of God. Thus, the traditions merged.
