Tobit 12:16-22

16 Then they were both troubled, and fell upon their faces: for they feared.
17 But he said unto them, Fear not, for it shall go well with you; praise God therefore.
18 For not of any favour of mine, but by the will of our God I came; wherefore praise him for ever.
19 All these days I did appear unto you; but I did neither eat nor drink, but ye did see a vision.
20 Now therefore give God thanks: for I go up to him that sent me; but write all things which are done in a book.
21 And when they arose, they saw him no more.
22 Then they confessed the great and wonderful works of God, and how the angel of the Lord had appeared unto them.
