The upper/western ridge of the city is where the wealthier residents of Jerusalem lived (the large homes with the red tiled roofs). It is here where High Priest Ciaphas lived along with members of the Sanhedrin and temple controlling Sadducees. It is probably in this sector of the city where prior to the feast day of Passover that the "chief priests and the scribes" met (probably on the Wednesday) to determine "how they might take him by craft, and put him to death." (Mark 14:1)
While the leaders of the Jews were conspiring against Jesus, he seems to have spent the day out of the public eye. The one recorded event (the gospels varying on the day of this event) happened in Bethany where Jesus may have spent the day among friends.
3 ¶And being in Bethany in the house of Simon the leper, as he sat at meat, there came a woman having an alabaster box of ointment of spikenard very precious; and she brake the box, and poured it on his head.
4 And there were some that had indignation within themselves, and said, Why was this awaste of the ointment made?
5 For it might have been sold for more than three hundred pence, and have been given to the poor. And they murmured against her.
7 For ye have the apoor with you always, and whensoever ye will ye may do them good: but me ye have not always.
8 She hath done what she could: ashe is come aforehand to anoint my body to the burying.
9 Verily I say unto you, Wheresoever this gospel shall be preached throughout the whole world, this also that ashe hath done shall be spoken of for a memorial of her.
By day's end Judas had set in motion his betrayal.
10 ¶And Judas Iscariot, one of the twelve, went unto the chief priests, ato betray him unto them.
