If you listen to the voice of the Lord, your God, and you do what is right in his sight, if you listen to his ordinances and observe all of his laws, I will not bring upon you any of the diseases that I brought upon the Egyptians, for I am the Lord, who heals you.
My son, concentrate attentively on my words; pay heed to the instructions I pass on to you. Do not let them slip from your mind; keep them forever in your heart.
