Like a partridge that hatches eggs it did not lay are those who gain riches by unjust means. When their lives are half gone, their riches will desert them, and in the end they will prove to be fools.
They must be silenced, because they are disrupting whole households by teaching things they ought not to teach—and that for the sake of dishonest gain.
In their greed these teachers will exploit you with fabricated stories. Their condemnation has long been hanging over them, and their destruction has not been sleeping.
