The land promise was given to Abraham right?...
Romans 9:6-8, "However, it is not as though Yahweh's plan had failed. For it is not everyone who is a descendant of Israyl who belongs to Israyl. Nor, just because they are his descendants, are they all Abraham's children; but: In Isaac will your seed be called. That is, it is not those who are the children of the flesh who are Yahweh's children; but it is the children of the promise who are regarded as Abraham's seed."

We are also given a possession. It is a place where God has put all of His children according to his divine plan for each of us. God's commandments to Israel then are in perfect step with how he wants us to cling to our possession.
