וְעַתָּ֣ה יִשְׂרָאֵ֗ל שְׁמַ֤ע אֶל־הַֽחֻקִּים֙ וְאֶל־הַמִּשְׁפָּטִ֔ים אֲשֶׁ֧ר אָֽנֹכִ֛י מְלַמֵּ֥ד אֶתְכֶ֖ם לַעֲשׂ֑וֹת לְמַ֣עַן תִּֽחְי֗וּ וּבָאתֶם֙ וִֽירִשְׁתֶּ֣ם אֶת־הָאָ֔רֶץ אֲשֶׁ֧ר יְהוָ֛ה אֱלֹהֵ֥י אֲבֹתֵיכֶ֖ם נֹתֵ֥ן לָכֶֽם׃
And now, O Israel, hearken unto the statutes and unto the ordinances, which I teach you, to do them; that ye may live, and go in and possess the land which the LORD, the God of your fathers, giveth you.
