לְאַֽהֲבָה֙ אֶת־יְהוָ֣ה אֱלֹהֶ֔יךָ לִשְׁמֹ֥עַ בְּקֹל֖וֹ וּלְדָבְקָה־ב֑וֹ כִּ֣י ה֤וּא חַיֶּ֙יךָ֙ וְאֹ֣רֶךְ יָמֶ֔יךָ לָשֶׁ֣בֶת עַל־הָאֲדָמָ֗ה אֲשֶׁר֩ נִשְׁבַּ֨ע יְהוָ֧ה לַאֲבֹתֶ֛יךָ לְאַבְרָהָ֛ם לְיִצְחָ֥ק וּֽלְיַעֲקֹ֖ב לָתֵ֥ת לָהֶֽם׃ (פ)
to love the LORD thy God, to hearken to His voice, and to cleave unto Him; for that is thy life, and the length of thy days; that thou mayest dwell in the land which the LORD swore unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
Targum Jonathan on Deuteronomy
that you may love the Lord thy God, to obey His Word, and keep close unto His fear; for the law in which you occupy yourselves will be your life in this world, and the prolongment of your days in the world that cometh; and you shall be gathered together at the end of the scattering, and dwell upon the land which the Lord sware to your fathers, to Abraham, Izhak, and Jakob, to give it unto them.
