וְהָיְתָ֣ה עִמּ֔וֹ וְקָ֥רָא ב֖וֹ כָּל־יְמֵ֣י חַיָּ֑יו לְמַ֣עַן יִלְמַ֗ד לְיִרְאָה֙ אֶת־יְהוָ֣ה אֱלֹהָ֔יו לִ֠שְׁמֹר אֶֽת־כָּל־דִּבְרֵ֞י הַתּוֹרָ֥ה הַזֹּ֛את וְאֶת־הַחֻקִּ֥ים הָאֵ֖לֶּה לַעֲשֹׂתָֽם׃
E estará com ele, e nele lerá todos os dias de sua vida, para que aprenda a temer a Yehovah seu Elohim, guardando todas as palavras desta Torá e estes estatutos, para fazê-los.
Jerusalem Talmud Sanhedrin
“If he goes to war, he carries it with him for it is said: It shall be with him, and he shall read in it all the days of his life. Is there not an inference de minore ad majus? Since for a king of Israel, who was occupied by the needs of Israel, is it said that he shall read in it all the days of his life, a private person so much more. Similarly, it was said to Joshua: You shall meditate about it day and night204Jos. 1:8.. Is there not an inference de minore ad majus? Since for Joshua, who is occupied by the needs of Israel, it is said: you shall meditate about it day and night, then certainly a private person.
