אֲשֶׁ֨ר אָנֹכִ֣י מְצַוְּךָ֮ הַיּוֹם֒ לְאַהֲבָ֞ה אֶת־יְהוָ֤ה אֱלֹהֶ֙יךָ֙ לָלֶ֣כֶת בִּדְרָכָ֔יו וְלִשְׁמֹ֛ר מִצְוֺתָ֥יו וְחֻקֹּתָ֖יו וּמִשְׁפָּטָ֑יו וְחָיִ֣יתָ וְרָבִ֔יתָ וּבֵֽרַכְךָ֙ יְהוָ֣ה אֱלֹהֶ֔יךָ בָּאָ֕רֶץ אֲשֶׁר־אַתָּ֥ה בָא־שָׁ֖מָּה לְרִשְׁתָּֽהּ׃
in that I command thee this day to love the LORD thy God, to walk in His ways, and to keep His commandments and His statutes and His ordinances; then thou shalt live and multiply, and the LORD thy God shall bless thee in the land whither thou goest in to possess it.
