13  ... Why do we need the Blood (of the Lamb without spot and blemish)? The Scriptures contain the answer, "For there is not a just man on earth who does good and does not sin" Ecclesiastes 7:20."The soul who sins shall die" Ezekiel 18:20. All sinners must die … "for the wages of sin is death, but the gift of God is eternal life in Jesus our Lord" (Romans 6:23). As John the Baptist said."Behold the Lamb of God who takes away the sin of the world!" John 1:29.
"Therefore remember that you, once Gentiles in the flesh, who are called Uncircumcision by what is called the Circumcision, made in the flesh by hands. That at that time you were without the Messiah, being aliens from the commonwealth of Israel and strangers from the covenants of promise. Having no hope and without God in the world. Now, in Jesus the Messiah you who once were far off have been brought near by His blood. For He Himself is our peace, who has made both one, and has broken down the middle wall of separation. Having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace and that He might reconcile them both to God in one body through the Cross" Ephesians 2:11-1

Blood (Exodus 7:19-20) The Nile river, the longest in the known world was worshipped, so God had it turned into blood and all life in it died.

Boils (Exodus 9:8-9) God gave them boils, even their magicians had them, showing their powerlessness.

Frogs (Exodus 8:1-15) Heka, their goddess of intelligence, was represented by a frog, so God had them knee deep in frogs everywhere.

Hail (Exodus 9:23-25) Horus, the falcon sky god, was defeated as God had their crops destroyed by great hail mixed with fire.

Lice (Exodus 8:16-21) The one thing Egypt's magicians could not produce was lice, so lice covered the people and their animals.

Locusts (Exodus 10:12-15) The locusts ravaged whatever the hail left.

Beasts (Exodus 8:24) The god Set. represented by a crocodile, had its own temples and priests, so God sent them wild beasts.

Darkness (Exodus 10:22-23) Ra, the hawk sun god, was defeated by three days of total darkness that could be felt.

Plague (Exodus 9:1-6) Their chief god was Apis, a bull, and they worshipped Osiris, a goat, and Isis, a cow, so God had the cattle killed with a plague.
Death (Exodus 12:29) The Egyptians would have had all the Hebrew sons killed, so God had their firstborn sons killed on the first Passover
