The blueness — Grievous wounds, which make men black and blue; or severe punishments. Cleanseth — Are the means to reclaim a wicked man, and to purge out his corruption. The belly — Of the heart. Grievous wounds or stripes cleanse not only the outward man by keeping it from evil actions, but even the inward man, by expelling or subduing vile affections: which is a great and blessed benefit of afflictions.
