Another translation (New Revised Standard Version Catholic Edition) reads:
Although you were watching me, I really did not eat or drink anything—but what you saw was a vision.
Perhaps someone familiar with manuscripts and translation could comment.
It’s a difference between the Greek version
s and the Vulgate. So yeah, it all boils down
to differences between the various versions of Tobit.
Aramaic (4Q196 17 i 2): “When I [w]as with you, …] I did [n]ot drink …]”
Greek II: καὶ ἐθεωρεῖτέ με ὅτι οὐκ ἔφαγον οὐθέν, ἀλλὰ ὅρασις ὑμῖν ἐθεωρεῖτο. “Now you were watching me; I did not eat anything, but a vision was being seen by you.”
Greek I: πάσας τὰς ἡμέρας ὠπτανόμην ὑμῖν, καὶ οὐκ ἔφαγον οὐδὲ ἔπιον, ἀλλὰ ὅρασιν ὑμεῖς ἐθεωρεῖτε. “All the days I appeared to you, but I did not eat or drink; rather, you were seeing a vision.”
Vetus Latina (Sangermanensis 15): Uidebatis enim me quia manducabam sed uisu uestro uidebatis. “For you used to see me eating, but you were seeing with your own (faculty of) sight.”
Vetus Latina (Monacensis; Munich, Bayerische Staatsbibliothek Clm 6239): Nam et quando uidebatis me manducantem uisui uestro uidebatis me quia bibebam. “And when you saw me eating, you were seeing with your own sight that I was drinking.”
Vetus Latina (Bobbiensis): Et uidebatis me quia manducabam sed uiso uestro uidebatis. “And you used to see me eating, but you were seeing with your own sight.”
Vetus Latina (Ripoll Bible): Quia qum uidebatis me manducare uisu uestro uidebatis. “For you who saw me eat, you were seeing with your sight.”
Vulgate: Uidebar quidem uobiscum manducare et bibere sed ego cibo inuisibili et potu qui ab hominibus uideri non potest utor. “I seemed indeed to eat and drink with you, but I use invisible food and a drink that cannot be seen by human beings.”
