The whole of the law itself became the law of gain to them, the law of sin and death or the law of Moses. Even the Psalms became law to them according to Jesus. They searched for eternal life in the scriptures to gain as if it were merchandise as to be bought and sold (Laodicea/ increased with goods, like children in the market place). As something to be gained. An earhtly thing, like the corruptible image of a man.
This was not the law of life that abided in the cloud upon the mount.
