I tell you, my friends, do not fear those who kill the body, and after that have nothing more that they can do.
Luke 12:4

...but the one who denies me before men will be denied before the angels of God.
Luke 12:9

Don't fear Pharaoh or any other "kings" of this world. You serve the King of all Kings. They all answer to him. Rather, fear God and his emissaries. Deny Yeshua and you will never leave Egypt. Repentance from sin and atonement by the blood of the Lamb is your one and only ticket out.
