Tobit is a classic example of an “entertaining angels unaware” story. When Tobit cried out to God for help, God immediately answered him by sending Raphael. But, as is often the case, God’s deliverance was not noticed at first. Raphael introduced himself as “Azariah,” which means “Yahweh helps,” and then rattles off a string of supposed mutual relations, all with names meaning things like “Yahweh is merciful,” “Yahweh gives,” and “Yahweh hears.” By this device, the author is saying (with a nudge and a wink), “Psst, audience. Get it?” And we, of course, do get it, particularly if we’re reading the story in the original Hebrew. Indeed, by using the name “Yahweh helps,” Raphael isn’t so much “lying” about his real name as he is revealing the deepest truth about who God is and why God sent him to Tobit.
