Numbers 18:18

וּפְדוּיָו מִבֶּן־חֹדֶשׁ תִּפְדֶּה בְּעֶרְכְּךָ כֶּסֶף חֲמֵשֶׁת שְׁקָלִים בְּשֶׁקֶל הַקֹּדֶשׁ עֶשְׂרִים גֵּרָה הֽוּא

And their redemption-money—from a month old shalt thou redeem them—shall be, according to thy valuation, five shekels of silver, after the shekel of the sanctuary—the same is twenty gerahs.

אַךְ בְּֽכוֹר־שׁוֹר אֽוֹ־בְכוֹר כֶּשֶׂב אֽוֹ־בְכוֹר עֵז לֹא תִפְדֶּה קֹדֶשׁ הֵם אֶת־דָּמָם תִּזְרֹק עַל־הַמִּזְבֵּחַ וְאֶת־חֶלְבָּם תַּקְטִיר אִשֶּׁה לְרֵיחַ נִיחֹחַ לַֽיהוָֽה

But the firstling of an ox, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt dash their blood against the altar, and shalt make their fat smoke for an offering made by fire, for a sweet savour unto the LORD.

כֹּל תְּרוּמֹת הַקֳּדָשִׁים אֲשֶׁר יָרִימוּ בְנֵֽי־יִשְׂרָאֵל לַֽיהוָה נָתַתִּֽי לְךָ וּלְבָנֶיךָ וְלִבְנֹתֶיךָ אִתְּךָ לְחָק־עוֹלָם בְּרִית מֶלַח עוֹלָם הִוא לִפְנֵי יְהוָה לְךָ וּלְזַרְעֲךָ אִתָּֽךְ

All the heave-offerings of the holy things, which the children of Israel offer unto the LORD, have I given thee, and thy sons and thy daughters with thee, as a due for ever; it is an everlasting covenant of salt before the LORD unto thee and to thy seed with thee.’

וַיֹּאמֶר יְהוָה אֶֽל־אַהֲרֹן בְּאַרְצָם לֹא תִנְחָל וְחֵלֶק לֹא־יִהְיֶה לְךָ בְּתוֹכָם אֲנִי חֶלְקְךָ וְנַחֲלָתְךָ בְּתוֹךְ בְּנֵי יִשְׂרָאֵֽל

And the LORD said unto Aaron: ‘Thou shalt have no inheritance in their land, neither shalt thou have any portion among them; I am thy portion and thine inheritance among the children of Israel.
