Exodus 12 - Ordination of Priests

The law defines the high priest's garments, which includes the twelve tribes of Israel for a remembrance to God. The ordination of priests also includes an ablution which relates to baptism, which can be seen also in Heb 6:1f. God also identifies things that are holy and not for outsiders in the ordination process. There is also a description of the incense altar in the tabernacle.

The people would be taxed for the upkeep of the temple, and this was a way to show the participation of the people in atonement for their sins.

Before the close of the revelation at Sinai, God reiterates the importance of keeping the Sabbath.  The tablets are then completed and given to Moses.
