Such is the account of the symbolic cleansing and the representative ministry of the Levites; and we see both a parallel and a contrast to what is demanded now for the Christian life of obedience and devotion to God. Purification there must be from all defilement of flesh and spirit. With the change which takes place when by repentance and faith in Christ we enter into the free service of God there must be a definite and earnest purging of the whole nature. "As ye presented your members as servants to uncleanness and to iniquity unto iniquity, even so now present your members as servants to righteousness unto sanctification" (Rom. vi. 19). "Mortify therefore your members which are upon the earth; fornication, uncleanness, passion, evil desire, and covetousness, the which is idolatry, ... put ye also away all these: anger, wrath, malice, railing, shameful speaking out of your mouth: lie not one to another; seeing that ye have put off the old man with his doings, and have put on the new man" (Col. iii. 5, 8, 9). Thus the purity of heart and soul so imperfectly represented by the cleansings of the Levites is set forth as the indispensable preparation of the Christian. And the contrast lies in this, that the purification required by the New Testament law is for all, and is the same for each. Whether one is to serve in the ministry of the Gospel or sweep a room as for God's cause, the same profound purity is needful. All in the Kingdom of God are to be holy, for He is holy.
The sacred service of the Levites is described in detail. There are three divisions, the Gershonites, the Kohathites, the Merarites. The Gershonites, from a month old and upward, number 7,500; the Kohathites, 8,600; the Merarites, 6,200. Eleazar, son of Aaron, is prince of the princes of the Levites.
The office of the Kohathites is of peculiar sanctity, next to that of Aaron and his sons. They are not "cut off" or specially separated from among the Levites (iv. 18); but they have duties that require great care, and they must not venture to approach the most holy things till preparation has been made by the priests. The manner of that preparation is fully described. When order has been given for the setting forward of the camp, Aaron and his sons cover the ark of the covenant first with the veil of the screen, then with a covering of sealskin, and lastly with a cloth of blue; they also insert in the rings the long staves with which the ark is to be carried. Next the table of shewbread is covered with a blue cloth; the dishes, spoons, bowls, and cups are placed on the top, over them a scarlet cloth, and above that a sealskin covering; the staves of the table are also placed in readiness. The candlestick and its lamps and other appurtenances are wrapped up in like manner and put on a frame. Then the golden altar by itself, and the vessels used in the service of the sanctuary by themselves are covered with blue cloth and sealskin and made ready for carriage. Finally, the great altar is cleansed of ashes, covered up with purple cloth and sealskin, and its staves set in their rings. When all this is done the sons of Kohath may advance to bear the holy things, never touching them lest they die.
