And Raphael said to them, Peace be unto you; fear not; bless the Lord for these great and wonderful things which he hath done unto you. Now as to myself, all the time I was with you ye saw me eat and drink, for so it appeared to your eyes, yet I did neither eat nor drink. Now therefore write you all these things in a book, and it shall be for a witness between you and your God all the days of your lives, and this thing shall be for a sign and a witness amongst all generations. And bless the Lord, and praise the remembrance of his holiness. And now let me go, and I will go to the God who sent me to you. So they sent him away, and blessed the Lord for all this. And the angel of the Lord went up to heaven, and appeared no more to Tobi and his son Tobiyyah.
