Adam Clarke's Commentary on the Bible

Verse 19 (Mark 7:19)

Into the draught - See on Matthew 15:17 ; (note).

Purging all meats? - For what is separated from the different aliments taken into the stomach, and thrown out of the body, is the innutritious parts of all the meats that are eaten; and thus they are purged, nothing being left behind but what is proper for the support of the body.
