The LORD wanted an altar to be made for the incense to be burned. The Israelites were to pay an offering to the LORD, a ransom for their life. Aaron and his sons were to wash their hands and feet in the basin before they were to enter the tent of meeting. The anointing oil was to be used to anoint the tent of meeting and other things. The incense was to be grinded and placed in front of the testimony in the Tent of Meeting.
