(4) Aaron and his sons thou shalt bring unto the door . . . --The place of the laver, not yet mentioned, but designed in God's counsels, was between the brazen altar and the Tabernacle (Exodus 30:18), and consequently near the door of the latter. Rabbinical tradition says that it was not placed exactly opposite the door, but a little towards the south side of the court.

And shalt wash them.--This is the first mention in Scripture of a religious ablution. Water is so natural a symbol of purity, and ablution so apt a representative of the purging from sin, that we can feel surprise neither at the widespread use of the symbolism in religions of very different characters, nor at its adoption into the system at this time imposed by Divine Providence upon the Hebrews. As it was to maintain its place even in the Divinely-appointed ceremonial of Christianity, it must have been a fortiori suitable for the earlier and less spiritual dispensation. The widespread employment of it in other religions--e.g., in Egypt (Herod. ii. 37); in Persia (Zendavesta, 8 p. 271. Spiegel's translation); in Greece (D�llinger, Jew and Gentile, vol. i., p. 220); in Italy (Dict. of Greek and Rom. Antiq., p. 719), and elsewhere--was no argument against its adoption into the Mosaic ceremonial, since the Divine legislation of Sinai was not intended to annul or supersede natural religion, but only to improve and expand it.

Verse 4. - The Ablution. Verse 4. - Unto the door of the tabernacle. The great laver was to be placed between the entrance to the tabernacle and the altar of burnt-offering (Exodus 30:18). It was to this probably that Aaron and his sons were to be brought. Its main purpose was to be a lustral vessel, placed ready for the various ablutions which the law required (ib, 19-21). Thou .... shalt wash them with water. Ablutions were an important part of the ceremonial of almost all ancient religions. In Egypt, the priests were compelled to wash themselves from head to foot in cold water twice every day, and twice every night (Herod. 2:37). In the religion of Zoroaster frequent washing with water was prescribed for many kinds of impurity (Zendavesta, 8. p. 271, et seq.). The Greeks were particularly addicted to ceremonies of which ablution formed a part; and it is to Rome that we are indebted both for the word and for the idea of "lustration." It is a true instinct which has taught men the analogy between physical and moral purity, and led them to typify the removal of spiritual, by the cleansing from physical, defilement. The religion given at Sinai set a stamp of approval in many points on what may be called "the religion of nature;" and among them on this. Ablutions were required of the priests, not only at consecration, but every time that they entered the tabernacle, or sacrificed on the altar of burnt-offering (Exodus 30:20). Washing was a main feature in the cleansing of leprosy (Leviticus 13:54, 58) and of the leper. (Leviticus 14:8). It was also employed for the purification of many minor defilements (Leviticus 11:25; Leviticus 15:5; Leviticus 17:15, etc.). At what date it first came into use in the admission of proselytes is uncertain. Whether the washing of consecration extended to the whole body, or was limited to the hands and feet, is also a point on which critics have disagreed, but one of no great importance. (See John 13:9, 10.)

29:1-37 Aaron and his sons were to be set apart for the priest's office, with ceremony and solemnity. Our Lord Jesus is the great High Priest of our profession, called of God to be so; anointed with the Spirit, whence he is called Messiah, the Christ; clothed with glory and beauty; sanctified by his own blood; made perfect, or consecrated through sufferings, Heb 2:10. All believers are spiritual priests, to offer spiritual sacrifices,And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation,.... That is, order and direct them to come thither; for it cannot be thought he was to carry them in his arms or on his shoulders, or have them thither by force, whether they would or not; but he was to declare to them that it was the will of the Lord they should appear there:

and shalt wash them with water; out of the laver after mentioned, which stood between the door of the tabernacle of the congregation and the altar: the Targum of Jonathan says, this washing was performed in forty seahs of living or spring water, which was sufficient for the immersion of the whole body, which it is highly probable was the case; and so Jarchi interprets it of the dipping of the whole body, and which seems to have been necessary, upon their entrance on their office, to denote their complete purity and holiness, though afterwards, when they entered on service, they only washed their hands and feet, see Exodus 30:18 to which our Lord seems to allude, John 13:10 this washing shows what purity and holiness were necessary to the priests of the Lord, and that they ought to be clean that bear the vessels of his house, or minister in his sanctuary, and which were in Christ in their full perfection; and such an high priest became us, who is holy, harmless, and undefiled, and so could offer himself without spot, and was a fit person to take away sin by sacrifice, and to be an advocate for his people: this may also point at his baptism, which he submitted to before he entered on his office in a public manner, and which was performed by immersion; and in this way ought all his priests, his saints, to be washed, as well as with the washing of regeneration, and with the blood of Christ; and which is necessary to their officiating as priests, or drawing nigh to God, and requisite to their communion with God and Christ.
