KJV:

16 Thus saith the Lord GOD; If the prince give a gift unto any of his sons, the inheritance thereof shall be his sons'; it shall be their possession by inheritance.
17 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.

18 Moreover the prince shall not take of the people's inheritance by oppression, to thrust them out of their possession; but he shall give his sons inheritance out of his own possession: that my people be not scattered every man from his possession.

NASB:

16 'Thus says the Lord GOD, "If the prince gives a gift out of his inheritance to any of his sons, it shall belong to his sons; it is their possession by inheritance.
17 "But if he gives a gift from his inheritance to one of his servants, it shall be his until the year of liberty; then it shall return to the prince. His inheritance shall be only his sons'; it shall belong to them.
18 "The prince shall not take from the people's inheritance, thrusting them out of their possession; he shall give his sons inheritance from his own possession so that My people will not be scattered, anyone from his possession."'"

‫טז  כֹּה-אָמַר אֲדֹנָי יְהוִה, כִּי-יִתֵּן הַנָּשִׂיא מַתָּנָה לְאִישׁ מִבָּנָיו--נַחֲלָתוֹ הִיא, לְבָנָיו תִּהְיֶה: אֲחֻזָּתָם הִיא, בְּנַחֲלָה. {ס}

‫יז  וְכִי-יִתֵּן מַתָּנָה מִנַּחֲלָתוֹ, לְאַחַד מֵעֲבָדָיו--וְהָיְתָה לּוֹ עַד-שְׁנַת הַדְּרוֹר, וְשָׁבַת לַנָּשִׂיא; אַךְ, נַחֲלָתוֹ--בָּנָיו, לָהֶם תִּהְיֶה.

‫יח  וְלֹא-יִקַּח הַנָּשִׂיא מִנַּחֲלַת הָעָם, לְהוֹנֹתָם מֵאֲחֻזָּתָם--מֵאֲחֻזָּתוֹ, יַנְחִל אֶת-בָּנָיו: לְמַעַן אֲשֶׁר לֹא-יָפֻצוּ עַמִּי, אִישׁ מֵאֲחֻזָּתוֹ.
