Ezekiel 34:19
And as for my flock, they eat that which ye have trodden with your feet; and they drink that which ye have fouled with your feet. And as for my flock, they eat that which ye have trodden with your feet; and they drink that which ye have fouled with your feet.
Ezekiel 34:19 belongs to a warning against being deceived and acting as unfaithful shepherds, with its picture of the flock eating trampled pasture and drinking fouled water showing the harm such shepherds bring to those in their care. The guilty false shepherds are the priests, rulers, and ministers who should have shepherded God's people as His sheep, but who act without the fear and love of God and without true commission, so that their neglected work does not have heaven's seal. They eat up the good pasture and drink of the deep waters themselves, keeping the good for themselves. They then tread down the residue of the pastures with their feet and foul the residue of the waters, so that God's flock must eat what has been trodden and drink what has been fouled, deprived of clean nourishment and harmed by those who should feed it.
Spiritually this means rejecting truth, trampling God's law, destroying the plain paths, withholding the nourishing message of saving truth while claiming God's promises, making the law contemptible including by speaking against the Sabbath, and failing to bless the needy and helpless with comfort, sympathy, and tender regard. The remedy is the one explained in Isaiah 58: feeding the hungry with truth and righteousness and restoring the paths by returning to loyalty to God, including honoring the Sabbath. In another application, drinking of the deep waters means having drunk deeply of truth and of the Sabbath, and fouling the residue with the feet means afterward treading the Sabbath underfoot.
Those described in this way are people who once kept the Sabbath and then gave it up. Some of them believed in Christ's coming and taught it with energy. For trampling the Sabbath they are weighed in the balance and found wanting, with that sentence written on their garments in large characters, and are left howling in agony and wailing aloud.
