מִלְּבַ֖ד שַׁבְּתֹ֣ת יְּהוָ֑ה וּמִלְּבַ֣ד מַתְּנֽוֹתֵיכֶ֗ם וּמִלְּבַ֤ד כָּל־נִדְרֵיכֶם֙ וּמִלְּבַד֙ כָּל־נִדְב֣וֹתֵיכֶ֔ם אֲשֶׁ֥ר תִּתְּנ֖וּ לַיהוָֽה׃
beside the sabbaths of the LORD, and beside your gifts, and beside all your vows, and beside all your freewill-offerings, which ye give unto the LORD.
