"I'll restore each to his own heritage each to his own land if they learn the ways of my people, as the King lives" Jeremiah 12:16.
In your lands welfare you will find your welfare - not in someone else's land.
"And seek the welfare of the land of which I have carried you into exile and pray to the King on it's behalf for in it's welfare, you will find your welfare in your own land." Jeremiah 29:7-8.
You cannot worship two Gods. It is high treason. You cannot drink from the cup of the Lord and the cup of the Baal Worshipper. "It is easier for a camel to get through a needle's eye than for a Baal Worshipper to get into the kindom of God. Matthew 19:24."
