And the priest shall take holy water in an earthen vessel; and of the dust that is in the floor of the tabernacle the priest shall take, and put it into the water:
The priest shall take holy water - water from the laver, which was to be mixed with dust-an emblem of vileness and misery (Genesis 3:14; Psalms 22:15).
In an earthen vessel. This fragile ware was chosen, because after being used it was broken in pieces (Leviticus 6:28; Leviticus 11:33).
