'Permanently' in the Bible

“I will make you pass under the rod [as the shepherd does with his sheep when he counts them, and I will count you as Mine and constrain you] and bring you into the bond of the covenant [to which you are permanently bound].

But if he gives a gift from his inheritance to one of his servants, then it shall be his until the year of liberty [the Year of Jubilee]; after that it shall be returned to the prince. His inheritance shall be only his sons’ [permanently]; it shall belong to them.
