And the LORD said unto Moses, Bring Aaron's rod again before the testimony, to be kept for a token against the rebels; and thou shalt quite take away their murmurings from me, that they die not.
Bring Aaron's rod again before the testimony - i:e., either in the ark before the tables of stone (Ebrard's 'Comment. on Hebrews 9:4 ') or in a chest adjoining it (Davidson's 'Introduction,' 3:, p. 223; Owens 'Exposition of the Epistle to the Hebrews').
To be kept for a token against the rebels - for if, after all admonitions and judgments, seconded by miracles, the people should still rebel, they would certainly pay the penalty by death.
