(11) And he sprinkled thereof upon the altar seven times.--That is, the altar of burnt offering. This rite of sprinkling the altar seven times is not mentioned in the directions given in Exodus 30:28; Exodus 40:10. For the import of the number seven, see Leviticus 4:6.

And anointed the altar and all his vessels.--That is, the same altar of burnt sacrifice. The altar, having thus been sanctified, was thenceforward considered as sanctifying the sacrifices and oblations offered upon it. Hence the remark of Christ, "Ye fools and blind, for whether is greater, the gift, or the altar that sanctifieth the gift ?" (Matthew 23:19).

8:1-13 The consecration of Aaron and his sons had been delayed until the tabernacle had been prepared, and the laws of the sacrifices given. Aaron and his sons were washed with water, to signify that they ought to purify themselves from all sinful dispositions, and ever after to keep themselves pure. Christ washes those from their sins in his own blood whom he makes kings and priests to our God, Re 1:5,6; and those that draw near to God must be washed in pure water, Heb 10:22. The anointing of Aaron was to typify the anointing of Christ with the Spirit, which was not given by measure to him. All believers have received the anointing.And he sprinkled thereof upon the altar seven times,.... The altar of burnt offering; the order for anointing it is given in Exodus 30:28 but in that no directions are given for the manner of doing it by sprinkling, nor the number of times it was to be sprinkled: hence Jarchi confesses his ignorance, and says,"I know not how it was ordered about these sprinklings;''but no doubt Moses was instructed of God in what manner to anoint it, and how often; and the number seven may denote the perfect unction of it, and made it a fitter type of Christ, who received the unction of the Spirit without measure:

and anointed the altar, and all its vessels; pans, shovels, basins, flesh hooks, and fire pans:

both the laver and his foot; which was for the priests to wash at; and very probably this was done before Moses brought Aaron and his sons thither and washed them, Leviticus 8:6 since it seems most proper that it should be consecrated before used, as it follows:

to sanctify them; set them apart for sacred use.
