Números 19

Números 19:15

The cover of a vessel, or a seal, is the control of discipline. Discipline keeps a man from being overwhelmed, as if he were an unclean or polluted vessel that is rejected. For a vessel without a cover or a seal is spoiled, like as in the case of one who devotes himself to ostentation and is not covered by any veil of silence. — EXPOSITION OF THE OLD AND NEW TESTAMENT, NUMBERS 15
