The Lord protects the untrained; I was in serious trouble and he delivered me.

Your instructions are a doorway through which light shines. They give insight to the untrained.

I have indeed heard the people of Israel say mournfully, 'We were like a calf untrained to the yoke. You disciplined us and we learned from it. Let us come back to you and we will do so, for you are the Lord our God.
