“Jesus looked up.

He saw rich people

Putting their gifts

Into the treasury.”

Ἀναβλέψας δὲ εἶδεν τοὺς βάλλοντας εἰς τὸ γαζοφυλάκιον τὰ δῶρα αὐτῶν πλουσίους.

Luke indicated that Jesus looked up (Ἀναβλέψας δὲ).  He saw (εἶδεν τοὺς) rich people (πλουσίους) putting, casting, or dropping their gifts into the treasury (βάλλοντας εἰς τὸ γαζοφυλάκιον τὰ δῶρα αὐτῶν).  Only Mark, chapter 21:41, has something similar, but in a more expansive form, while Matthew did not mention this incident.  Mark said that Jesus sat down opposite the treasury (Καὶ καθίσας κατέναντι τοῦ γαζοφυλακίου), that was a room in the Temple.  This room probably had many large containers, probably twelve receptacles for the various Israelite tribes, to put gifts into.  He watched how the crowds of people put money into the treasury containers (ἐθεώρει πῶς ὁ ὄχλος βάλλει χαλκὸν εἰς τὸ γαζοφυλάκιον).  Many rich people put in large sums of money (καὶ πολλοὶ πλούσιοι ἔβαλλον πολλά).  There is nothing extraordinary about rich people giving lots of money to the Temple treasury.  This seemed normal enough.  Do you contribute to religious organizations?
