Israel was given to Gods people long long ago.
“But if you or your sons turn away from me and do not observe the commands and decrees I have given you and go off to serve other gods and worship them, then I will cut off Israel from the land I have given them and will reject this temple I have consecrated for my Name.” (1 Kings 9:6-7)
But God found fault with the people and said, “The time is coming,” declares the Lord, “when I will make a new covenant with the house of Israel and with the house of Judah.” (Hebrews 8:8)
By calling this covenant “new,” He has made the first one obsolete; and what is obsolete and aging will soon disappear. (Hebrews 8:13)
Read all the verses you can find concerning the covenant, put them together without ignoring any of them, and I believe you’ll find the covenant concerning the land was conditional.
