Robin: Holy hand washing, Batman! It looks like Exodus 30 is all about the importance of cleanliness.

Batman: That's right, Robin. In this chapter, God instructs Moses to make a bronze basin and a stand for it, so that the priests can wash their hands and feet before they enter the Tabernacle.

Catwoman: And look, Batman! It says that the priests must also make an incense altar out of acacia wood with four horns!

Batman: Yes, Catwoman. But don't forget about the offering. We must all present an offering to the Lord: a half shekel of silver.

Riddler: What a perplexing puzzle! What's the importance of the silver offering?

Batman: Well, Riddler, the silver offering was used to fund the Tabernacle and its maintenance. It was also a reminder of the Israelites' responsibility to pay their tax to the Lord.
