וַֽיְעַנְּךָ֮ וַיַּרְעִבֶךָ֒ וַיַּֽאֲכִֽלְךָ֤ אֶת הַמָּן֙ אֲשֶׁ֣ר לֹא־יָדַ֔עְתָּ וְלֹ֥א יָדְע֖וּן אֲבֹתֶ֑יךָ לְמַ֣עַן הוֹדִֽעֲךָ֗ כִּ֠י לֹ֣א עַל־הַלֶּ֤חֶם לְבַדּוֹ֙ יִחְיֶ֣ה הָֽאָדָ֔ם כִּ֛י עַל־כָּל־מוֹצָ֥א פִֽי־יְהוָ֖ה יִחְיֶ֥ה הָאָדָֽם׃
And He afflicted thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that He might make thee know that man doth not live by bread only, but by every thing that proceedeth out of the mouth of the LORD doth man live.
Targum Jonathan on Deuteronomy
And He humbled thee and let thee hunger, and fed thee with the manna which thou knewest not, nor thy fathers had known, that He might make thee to know that man liveth not by bread only, but by all that is created by the Word of the Lord doth man live.
