And their pots hold the broth of unclean meat;

He who offers incense, as one who blesses an idol.
Such people have chosen their own ways,
And their soul delights in their repulsive acts;

Following after one in the center,
Who eat swine’s flesh, detestable things and mice,
Will come to an end together,” says the Lord.
