Ezekiel 46:16

We have here a law for the limiting of the power of the prince in the disposing of the crown-lands. 1. If he have a son that is a favourite, or has merited well, he may, if he please, as a token of his favour and in recompence for his services, settle some parts of his lands upon him and his heirs for ever (Eze 46:16), provided it do not go out of the family. There may be a cause for parents, when their children have grown up, to be more kind to one than to another, as Jacob gave to Joseph one portion above his brethren, Gen 48:22. 2. Yet, if he have a servant that is a favourite, he may not in like manner settle lands upon him, Eze 46:17. The servant might have the rents, issues, and profits, for such a term, but the inheritance, the jus proprietarium - the right of proprietorship, shall remain in the prince and his heirs. It was fit that a difference should be put between a child and a servant, like that Joh 8:35. The servant abides not in the house for ever, as the son does. 3.

The prince's possession is to be inalienable, and any portion given to a servant is to revert to his sons at the year of jubilee, that he may have no temptation to spoil his people of their inheritance, as formerly (compare Ahab and Naboth, 1Ki. 21:1-29). The mention of the year of jubilee implies that there is something literal meant, besides the spiritual sense. The jubilee year was restored after the captivity [JOSEPHUS, Antiquities, 14.10,6; 1 Maccabees 6:49]. Perhaps it will be restored under Messiah's coming reign. Compare Isa 61:2-3, where "the acceptable year of the Lord" is closely connected with the comforting of the mourners in Zion, and "the day of vengeance" on Zion's foes. The mention of the prince's sons is another argument against Messiah being meant by "the prince."
