Matthew 23:24 condemns straining gnats while swallowing camels — the priests scrupulously avoid the treasury yet are guilty of murder.

Deuteronomy 23:18 forbids bringing unclean money into God's house — the priests apply that to blood money but ignore the bloodshed.

John 18:28 shows them avoiding defilement for Passover while seeking Jesus's death — the same hypocrisy as here with blood money.

2 Kings 21:16 describes Manasseh shedding innocent blood — a parallel to the innocent blood behind this blood money, highlighting its defilement.
