Featured 3 days and 3 nights in the heart of the earth......starting Thursday night

Scripture doesn't tell us any of these details. We just have scripture suggesting he proclaimed victory to spirits sometime during his death. Could have been the whole time from Friday afternoon to the twilight of the morning first day when he rose. Or it just could have been a couple hours. We aren't told.

Again, heart of the earth is not a reference to the grave, nor to hades, anymore than belly of the whale is a reference to hades.

I don't understand what you're asking here, you'll have to restate.

If you believe heart of the earth is a reference to Jesus time in hades, then I can see why you believe he was there for 3 days and 3 nights. But I disagree with the premise that heart of the earth is a reference to hades.

Also, Jesus was in the actual grave (dead) for 3 days and 2 nights. So three days is an accurate description for his time in the grave. Three days and three nights, however, is not possible. Jesus must have been referring to something broader.

 

No idea, just something I came across. I don't have firm backup for it.

 

Most literally, it's a term for burial, especially when you understand what the word "earth" means in the Bible. It means land, therefore the phrase should be understood as under the land. Underground or buried would be the most literal and logical understanding. If someone says it doesn't mean this, I would say the onus is on them to provide an argument.

Phil. 2:10 that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth,

Rev. 5:3 And no one in heaven or on the earth or under the earth was able to open the scroll, or to look at it.

Rev. 5:13 And every creature which is in heaven and on the earth and under the earth and such as are in the sea, and all that are in them, I heard saying:

“Blessing and honor and glory and power

Be to Him who sits on the throne,

And to the Lamb, forever and ever!”​

This term was definitely out there for Jesus to use, but he didn't. He use

 

Yes, just as we often say we're in hell when in a dire situation. But there's nothing in the text to suggest that Jonah was literally in sheol, and not literally in the whale. There's nothing to suggest he left the whale and went to Sheol, and then came back.

But this is also irrelevant. Regardless of how I think of this, it doesn't have any bearing on the meaning of the term, "heart of the earth." One can agree with you that Jonah died at one point, and then was revived by God. Interesting, but irrelevant.

 

I think so yes, for the reasons I've mentioned. When you have a phrase that clearly means that, and it's not used, it casts doubts. And when you underhand the meaning of earth as land, it's like comparing the terms heartland and underground.
