Exodus 12:22

And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.

Prayer before Starting on a Journey

My holy Angel Guardian, ask the Lord to bless the journey which I undertake, that it may profit the health of my soul and body; that I may reach its end, and that, returning safe and sound, I may find my family in good health. Do thou guard, guide and preserve us. Amen. Prayer for Travelers O Almighty and merciful God, who hast commissioned Thy angels to guide and protect us, command them to be our assiduous companions from our setting out until our return; to clothe us with their invisible protection; to keep from us all danger of collision, of fire, of explosion, of fall and bruises, and finally, having preserved us from all evil, and especially from sin, to guide us to our heavenly home. Through Jesus Christ, our Lord. Amen.
