As a fifth aspect of how Scripture reveals that the land of Israel was special to God, consider what God did when He removed Israel from the Northern Kingdom for their wickedness:
2 Kings 17:23 Until the LORD removed Israel out of his sight, as he had said by all his servants the prophets. So was Israel carried away out of their own land to Assyria unto this day.
As a result of God's judgment, the Assyrian king subsequently settled pagans in the land of Israel who did not fear the Lord:
24 And the king of Assyria brought men from Babylon, and from Cuthah, and from Ava, and from Hamath, and from Sepharvaim, and placed them in the cities of Samaria instead of the children of Israel: and they possessed Samaria, and dwelt in the cities thereof. 25 And so it was at the beginning of their dwelling there, that they feared not the LORD: therefore the LORD sent lions among them, which slew some of them.
Notice carefully what God did on this occasion. Even though He had removed Israel from the land, He still cared whether or not those who were dwelling in that land feared Him. Because the pagans who were in that land then did not fear Him, God sent lions to punish them!
It is impossible to say that this passage shows that the land was only special because of the Israelites because if that were the case, God would not have cared what would have taken place in the land once the Israelites were out of the land.
The passage, however, clearly shows that God did care about what took place in that land even when the Israelites were no longer there!
As a result of what God did, the new inhabitants of the Northern Kingdom who were unbelievers somehow yet knew and told the Assyrian king that the God of the land was judging them because they did not know "the manner of the God of the land":
26 Wherefore they spake to the king of Assyria, saying, The nations which thou hast removed, and placed in the cities of Samaria, know not the manner of the God of the land: therefore he hath sent lions among them, and, behold, they slay them, because they know not the manner of the God of the land.
In response, the Assyrian king--who was an unbeliever-- ordered that one of the Israelite priests be sent back to teach the new inhabitants the manner of the God of the land:
27 Then the king of Assyria commanded, saying, Carry thither one of the priests whom ye brought from thence; and let them go and dwell there, and let him teach them the manner of the God of the land.
28 Then one of the priests whom they had carried away from Samaria came and dwelt in Bethel, and taught them how they should fear the LORD.
Even though the Israelites were no longer in the land--and never returned to the Northern Kingdom--God acted so that those who lived in that land still feared Him. Clearly, God wanted whoever inhabited that land to fear Him. His concern for that land was not at all only because the Israelites were there and only as long as they were there.
This passage definitively shows that the land of Israel was special to God even after He had expelled the Israelites from the Northern Kingdom!
