Comentario sobre Salmos 119:130

The commencement of Your words enlightens The beginning of your words enlightened the heart of Israel, that You understated the simple, by Your statement (Exod. 20:2): “I am...Who took you out.” You let them know the favor that You did for them—that You acquired them from the house of bondageto know that You are their Master, and they should accept Your kingdom upon themselves. (Exod. 20:3): “You shall not have another god, etc.” and afterwards You made Your decrees (Cf. Mechilta ad loc.). Another explanation: The commencement of Your words enlightens The beginning of Your words in the Creation was (Gen. 1:3): “Let there be light.”

You make the simple understand From there, everyone will understand and will commence with words of Torah. Tanchuma (Vayakhel 6).
