"Tell Aaron and his sons to be careful with the holy gifts of the sons of Israel, which they dedicate to Me, so as not to profane My holy name; I am the LORD.

Hebrew

ב דַּבֵּר אֶל-אַהֲרֹן וְאֶל-בָּנָיו, וְיִנָּזְרוּ מִקָּדְשֵׁי בְנֵי-יִשְׂרָאֵל, וְלֹא יְחַלְּלוּ, אֶת-שֵׁם קָדְשִׁי--אֲשֶׁר הֵם מַקְדִּשִׁים לִי, אֲנִי יְהוָה.
