Something to consider on the "three nights" that Christ spoke of:
The Sign of Jonah
…
39But He answered and said to them, "An evil and adulterous generation craves for a sign; and yet no sign will be given to it but the sign of Jonah the prophet;
40for just as JONAH WAS THREE DAYS AND THREE NIGHTS IN THE BELLY OF THE SEA MONSTER, so will the Son of Man be three days and three nights in the heart of the earth.
41"The men of Nineveh will stand up with this generation at the judgment, and will condemn it because they repented at the preaching of Jonah; and behold, something greater than Jonah is here.…
I was reading online and came across this article at the Calvary Training website:
"After the trial, but before the High Priest could send Jesus to stand before Pilot, Jesus was held for the night, cast into a pit there in the High Priest’s house.
It’s a site that tourist’s can visit, today.
Pastor Jon told us it was spoken of in Psalm 88.
Yahweh, the God of my salvation, I have cried day and night before you. 2 Let my prayer enter into your presence. Turn your ear to my cry. 3 For my soul is full of troubles.
My life draws near to Sheol. 4 I am counted among those who go down into the pit. I am like a man who has no help, 5 Set apart among the dead, Like the slain who lie in the grave, Whom you remember no more. They are cut off from your hand.
6 You have laid me in the lowest pit, In the darkest depths. 7 Your wrath lies heavily on me. You have afflicted me with all your waves. Selah. 8 You have taken my friends from me.
You have made me an abomination to them. I am confined, and I can’t escape.
9 My eyes are dim from grief. I have called on you daily, Yahweh. I have spread out my hands to you. 10 Do you show wonders to the dead? Do the dead rise up and praise you? Selah.
11 Is your lovingkindness declared in the grave? Or your faithfulness in Destruction?
12 Are your wonders made known in the dark? Or your righteousness in the land of forgetfulness?
13 But to you, Yahweh, I have cried. In the morning, my prayer comes before you. 14 Yahweh, why do you reject my soul? Why do you hide your face from me? 15 I am afflicted and ready to die from my youth up. While I suffer your terrors, I am distracted.
16 Your fierce wrath has gone over me. Your terrors have cut me off. 17 They came around me like water all day long. They completely engulfed me. 18 You have put lover and friend far from me, And my friends into darkness.
