"Now the Feast of Unleavened Bread drew near, which is called Passover. And the chief priests and the scribes sought how they might kill Him, for they feared the people. Then Satan entered Judas [...]" Luke 22:1-3
The Festal Day commemorating deliverance from Pharaoh draws near, commemorating the hunting angel of death thwarted by doors marked by the smeared life-blood of a lamb, commemorating the defeat of the tyrant Pharaoh and his drowning in the Sea with his troops as he closes in on them, he drowns who is typologically aligned with the Leviathan; the Pharaoh overlorded the Israelites like chattel to be herded and milked, and Moses shepherded, guided them like freemen.
During this Feast, the high ("chief") priests plot; their deathly attention is fixed on Jesus, this attention circling around him, closing in on him, waiting to pounce; it all must be done in the darkness, for the people -- whose will is their only light, and a dark light at that! -- must be managed like slaves (rather than shepherded like freemen). They would smear his blood to save themselves and their nationalized institutions (the house of God is no longer a house of prayer for all nations, but functions as a national treasury and a national flag of sorts, ethnocentric rather than theocentric) from the hunting eye of the Romans. Finally, as the darkness of murderous intent descends, Satan enters into Judas. This is anti-incarnation.
It all reminds me of the wickedness within Heorot immediately preceding, and calling forth, Grendel, as the appropriately monstrous manifestation of the spiritual rot within the Germanic "City on a Hill."
If such an entrance of Satan results from both his hatred of the Master and the murderous avarice of these high priests, and Grendel's marauding is the result of the kinslaying intent within Heorot, are not the material objects of our sin only the manifestation of, or are they rather not drawn to us (as much as us to them) by, the very particular form of rot in our own hearts? --and where is the Lord in such a case, that they would seek to kill Him?
