If, however, he makes a gift from his inheritance to one of his servants, the servant may keep it until the year of freedom; then it will revert to the prince. His inheritance belongs to his sons only; it is theirs.
NIV
But if he gives a gift out of 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; only his sons may keep a gift from his inheritance [permanently].
AMP
But if he give a gift of his inheritance to one of his servants, then it shall be his to the year of liberty; after it shall return to the prince: but his inheritance shall be his sons' for them.
