Commentary for Ezekiel 44:30

וְרֵאשִׁית֩ כָּל־בִּכּ֨וּרֵי כֹ֜ל וְכָל־תְּר֣וּמַת כֹּ֗ל מִכֹּל֙ תְּרוּמ֣וֹתֵיכֶ֔ם לַכֹּהֲנִ֖ים יִֽהְיֶ֑ה וְרֵאשִׁ֤ית עֲרִסֽוֹתֵיכֶם֙ תִּתְּנ֣וּ לַכֹּהֵ֔ן לְהָנִ֥יחַ בְּרָכָ֖ה אֶל־בֵּיתֶֽךָ׃

And the first of all the first-fruits of every thing, and every heave-offering of every thing, of all your offerings, shall be for the priests; ye shall also give unto the priest the first of your dough, to cause a blessing to rest on thy house.
