An Answer to the Riddle of Christ's  "Three Nights in the Heart of the Earth"

Christ predicted that He would be "in the heart of the Earth
for three days and three nights"(Matthew 12.40),
but we shouldn't insist on three nights in the tomb.
For He didn't say "in the tomb." Rather He said, "in the heart of the Earth."
He used that phrase DELIBERATELY.

Crucified on Friday, Christ rose on Sunday morning.
So he spent two nights in the tomb.
But he had been arrested Thursday night, and taken
to the basement of the High Priest's house(Luke 22.54).
He spent that night in the holding cell(a dungeon)
which has been preserved to this day.
(I saw it in 1973 while on a tour of the Holy Land.)
So Christ spent three nights below the surface of the ground:
(1)Thursday night in the holding cell (while He awaited trial
before the High Priest serving as Judge),
(2)Friday night in the tomb,
(3)Saturday night in the tomb.

Why is it important to see that Thursday night in the dungeon
is the first of the "three nights in the heart of the Earth"?!
Because some say Christ must have been crucified not on Friday
but on Thursday - Just so all three nights could be spent in the tomb.
Such revisionism is totally uncalled
for Church Tradition is not to be so easily discounted.
