15But let the stump and its roots, bound with iron and bronze, remain in the ground, in the grass of the field. “ ‘Let him be drenched with the dew of heaven, and let him live with the animals among the plants of the earth.

16Let his mind be changed from that of a man and let him be given the mind of an animal, till seven times Or years; also in verses 23, 25 and 32 pass by for him.
