“Moreover the prince shall not take of the people's inheritance, to thrust them out of their possession. He shall give inheritance to his sons out of his own possession, so that my people be not scattered every man from his possession.”
If the prince wanted his sons to have possessions, it must be out of his own portion. He was forbidden to give them land belonging to another. There must be no dispossessing of people in the land. All Israelites had a right to security of tenure.
Thus the rights of the princely line were both protected and restricted. They could not be permanently squandered, nor could they be permanently extended. Their position was safeguarded, and so were the positions of others.
Like all of Ezekiel's visions this had both short and long application. In the short term it was a pleasant dream which had little fulfilment, in the long term it described the equity and righteousness of the coming everlasting kingdom.
