'Occupying' in the Bible

So Joshua said to the Israelites: "How long do you intend to put off occupying the land the Lord God of your ancestors has given you?

The Lord says, "Enroll this man in the register as though he were childless. Enroll him as a man who will not enjoy success during his lifetime. For none of his sons will succeed in occupying the throne of David or ever succeed in ruling over Judah."
