Richard Sibbes said this quote

Moses, without any mercy, breaks all bruised reeds, and quenches all smoking flax. For the law requires personal, perpetual and perfect obedience from the heart, and that under a most terrible curse, but gives no strength. It is a severe task master, like Pharaoh's, requiring the whole tale ofbricks and yet giving no straw. Christ comes with blessing after blessing, even upon those whom Moses had cursed, and with healing balm for those wounds which Moses had made.
