SEV Biblia, Chapter 30:20
Cuando entraren en el tabernáculo del testimonio, se han de lavar con agua, para que no mueran; y cuando se llegaren al altar para ministrar, para encender al SEÑOR la ofrenda que se ha de consumir al fuego,
Clarke's Bible Commentary - Exodus 30:20
Verse 20. They shall wash with water, that they die not] This was certainly an emblematical washing; and as the hands and the feet are particularly mentioned, it must refer to the purity of their whole conduct. Their hands - all their works, their feet - all their goings, must be washed - must be holiness unto the Lord. And this washing must be repeated every time they entered into the tabernacle, or when they came near to the altar to minister. This washing was needful because the priests all ministered barefoot; but it was equally so because of the guilt they might have contracted, for the washing was emblematical of the putting away of sin, or what St. Paul calls the laver of regeneration and the renewing of the Holy Ghost, (Tit. iii. 5,) as the influences of the Spirit must be repeated for the purification of the soul, as frequently as any moral defilement has been contracted.
Matthew Henry Commentary
Verses 17-21 - A large vessel of brass, holding water, was to be set near the door of the tabernacle. Aaron and his sons must wash their hands and feet a this laver, every time they went in to minister. This was to teach the purity in all their services, and to dread the pollution of sin. The must not only wash and be made clean, when first made priests, but mus wash and be kept clean, whenever they went to minister. It teaches u daily to attend upon God, daily to renew our repentance for sin, an our looking to the blood of Christ for remission; for in many things we daily offend.
