Were
the LAND PROMISES to Israel already fulfilled?

The LAND PROMISES Fulfilled after their bondage in, and liberation from Egypt!
Joshua
21:43-45 So the LORD gave to Israel all the land which he swore to give to
their fathers; and having taken possession of it, they settled there. And the LORD gave them rest on every side just
as he had sworn to their fathers; not one of all their enemies had withstood
them, for the LORD had given all their enemies into their hands. Not one of all
the good promises which the LORD had made to the house of Israel had failed;
all came to pass.
Paul even proclaimed this (in the 1st century) in a Synagogue in Antioch, Pisidia (Asia minor - Modern day Turkey)
Acts
13:16-19 Then Paul stood up, and beckoning with his hand said, Men of
Israel, and you that fear God, give audience. The God of this people of
Israel chose our fathers, and exalted the people when they dwelt as
strangers in the land of Egypt, and with an high arm brought he them out
of it. And about the time of forty years suffered he their manners in
the wilderness. And when he had destroyed seven nations in the land of
Chanaan, HE DIVIDED THEIR LAND TO THEM BY LOT.
Is there any record of anyone disputing this with Paul? No, there's not!
The LAND PROMISES Fulfilled after their bondage in, and liberation from the Babylonian Captivity!
Nehemiah
9:8 And found his heart faithful before you, and made a covenant with him to
give the land of the Canaanites, the Hittites, the Amorites, and the
Perizzites, and the Jebusites, and the Girgashites, to give it, I say, to his
seed, and has performed your words; for you are righteous.
WELL?
