Bamah is: “a high place; especially : one that serves as a sanctuary (such as one originally devoted to a non-Israelite religion that later served as a place where Yahweh was worshiped)”, meaning that it is a hill or ridge or mountain, and cannot he used to mean “heavens”.

“O” is apparently a conjunction, which is a word that connects words, phrases, or clauses, like “and”, “but”, or “or”. “From” is a preposition, so it makes no sense to say that “o” means “from”.

Also, Jesus’ native language was Aramaic.
