וַיְהִ֥י דְבַר־יְהוָ֖ה אֵלַ֥י לֵאמֹֽר

The word of the LORD came to me:

בְּטֶ֨רֶם אצורך [אֶצָּרְךָ֤] בַבֶּ֙טֶן֙ יְדַעְתִּ֔יךָ וּבְטֶ֛רֶם תֵּצֵ֥א מֵרֶ֖חֶם הִקְדַּשְׁתִּ֑יךָ נָבִ֥יא לַגּוֹיִ֖ם נְתַתִּֽיךָ

Before I created you in the womb, I selected you; Before you were born, I consecrated you; I appointed you a prophet concerning the nations. 

Jeremiah 1:4-5
