And as for my flock, they eat that which ye have trodden with your feet,.... They are forced to do it, not being able to come at any thing else; being as sheep without a shepherd, or worse:and they drink that which ye have fouled with your feet; which, as it cannot be agreeable and relishing, so neither wholesome; as the leaven of the Scribes and Pharisees; the traditions of the elders; the false doctrines of false teachers, whose words eat as do a canker.
The Targum of the whole verse is,"and my people eat the residue of the food of your ministers, and drink the residue of the drink of your ministers.'
