Num 18:19

כֹּ֣ל תְּרוּמֹ֣ת הַקֳּדָשִׁ֗ים אֲשֶׁ֨ר יָרִ֥ימוּ בְנֵֽי־יִשְׂרָאֵל֮ לַֽיהוָה֒ נָתַ֣תִּֽי לְךָ֗ וּלְבָנֶ֧יךָ וְלִבְנֹתֶ֛יךָ אִתְּךָ֖ לְחָק־עוֹלָ֑ם בְּרִית֩ מֶ֨לַח עוֹלָ֥ם הִוא֙ לִפְנֵ֣י יְהוָ֔ה לְךָ֖ וּלְזַרְעֲךָ֥ אִתָּֽךְ׃

All the holy offerings that the Israelites present to the LORD I give to you and to your sons and daughters as a permanent statute. It is a permanent covenant of salt before the LORD for you and your offspring.”
