you can read MJ Agee's interesting treatise on Saturn/Heaven/Sapphire.
i don't know what i think about her concept, and i've been reading about it for years -
but i do note this:
first mention of Sapphire in the Bible is from this account in Exodus
"Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel:"
"And they saw the God of Israel: and there was under his feet as it were a paved work of a SAPPHIRE stone, and as it were the body of heaven in his clearness."
"And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink."
i do believe this is the first mention of a group of men gathered together before God to meet with Him, and they sit before Him, eating and drinking.
this seems to be a good Rapture type.
they ascend to where God is, they fellowship with Him (implied by eating and drinking), and it is a group of elders. First silver trumpet calls the Leaders.
no other detail about the appearance of God at this meeting is mentioned except the Sapphire pavement beneath His feet.
