I think this is the scene from Star Wars IV: A New Hope, that the comic is referencing:
THREEPIO: I see, sir.
LUKE: Uh, you can call me Luke.
THREEPIO: I see, sir Luke.
LUKE: (laughing) Just Luke.
THREEPIO: And I am See-Threepio, human-cyborg relations, and this is
my counterpart, Artoo-Detoo.
And also, from earlier in the movie, the img title references:
A voice calls out from one of the huge holes that form the
homestead. Luke goes over to the edge and sees his Aunt Beru
standing in the main courtyard.
BERU: Luke, tell Owen that if he gets a translator to be sure it
LUKE: It looks like we don't have much of a choice but I'll remind
Luke returns to his uncle as they look over the equipment
for sale with the Jawa leader.
OWEN: I have no need for a protocol droid.
THREEPIO: (quickly) Sir -- not in an environment such as this --
that's why I've also been programmed for over thirty secondary
OWEN: What I really need is a droid that understands the binary
language of moisture vaporators.
THREEPIO: Vaporators! Sir -- My first job was programming binary load
lifter...very similar to your vaporators. You could say...
OWEN: Do you speak Bocce?
THREEPIO: Of course I can, sir. It's like a second language for
me...I'm as fluent in Bocce...
OWEN: All right shut up! (turning to Jawa) I'll take this one.
THREEPIO: Shutting up, sir.

And the chapter in the Bible it's referencing is Exodus 3:
1 Now Moses was tending the flock of Jethro his father-in-law, the priest of Midian, and he led the flock to the far side of the desert and came to Horeb, the mountain of God. 2 There the angel of the LORD appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up. 3 So Moses thought, "I will go over and see this strange sight—why the bush does not burn up."
4 When the LORD saw that he had gone over to look, God called to him from within the bush, "Moses! Moses!"
And Moses said, "Here I am."
5 "Do not come any closer," God said. "Take off your sandals, for the place where you are standing is holy ground." 6 Then he said, "I am the God of your father, the God of Abraham, the God of Isaac and the God of Jacob." At this, Moses hid his face, because he was afraid to look at God.
13 Moses said to God, "Suppose I go to the Israelites and say to them, 'The God of your fathers has sent me to you,' and they ask me, 'What is his name?' Then what shall I tell them?"
14 God said to Moses, "I am who I am . [b] This is what you are to say to the Israelites: 'I AM has sent me to you.' "
