וְלָקַחְתָּ֞ אֶת־כֶּ֣סֶף הַכִּפֻּרִ֗ים מֵאֵת֙ בְּנֵ֣י יִשְׂרָאֵ֔ל וְנָתַתָּ֣ אֹת֔וֹ עַל־עֲבֹדַ֖ת אֹ֣הֶל מוֹעֵ֑ד וְהָיָה֩ לִבְנֵ֨י יִשְׂרָאֵ֤ל לְזִכָּרוֹן֙ לִפְנֵ֣י יְהוָ֔ה לְכַפֵּ֖ר עַל־נַפְשֹׁתֵיכֶֽם׃ (פ)
And thou shalt take the atonement money from the children of Israel, and shalt appoint it for the service of the tent of meeting, that it may be a memorial for the children of Israel before the LORD, to make atonement for your souls.’
