בְּטֶ֨רֶם אצורך [אֶצָּרְךָ֤] בַבֶּ֙טֶן֙ יְדַעְתִּ֔יךָ וּבְטֶ֛רֶם תֵּצֵ֥א מֵרֶ֖חֶם הִקְדַּשְׁתִּ֑יךָ נָבִ֥יא לַגּוֹיִ֖ם נְתַתִּֽיךָ׃
「我還沒有在腹中造你，就已經認識你；你還沒有出母胎，我就已經使你分別為聖；我立你作列國的先知。」
Mishneh Torah, Human Dispositions
He who follows such conduct will not only sanctify his soul, and live in a state of purity, and improve his ideas, but if he will father children they will be refined and modest, prepared for wisdom and piety; but he who follows the conduct of the rest of the people who walk in darkness will father children in their likeness.
