In the readings for today, as well as other days' readings, are listed many intricate details prescribed by God. Even though many of these things don't apply to us today in a literal sense, reading about them will be useful later on as a reference.  It is crystal clear that God is involved in the intricate details of their lives then.  The same is true for us today.  He expected strict obedience in these intricate details then.  He expects strict obedience with us today in whatever He asks us to do.

There are some rather unique instructions concerning the placement of the blood on Aaron and his sons for their consecration.  It is to be placed on the lobes of the right ears and the thumbs of the right hands and on their right big toes. Is this a reminder that they are to hear and do the work of the Lord?

There are many times the words “without yeast” appear in reference to presenting offerings to God. In the New Testament, Jesus warned us about the "yeast" of the Pharisees and Sadducees.
Matthew 16:11b-12
But be on your guard against the yeast of the Pharisees and Sadducees."Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.

Notice how many times the words “a pleasing aroma” appear in Scripture, followed every time in this day’s reading by the words, “an offering made to the Lord by fire.” What is the significance of that for us spiritually?
Romans 12:1
Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God-- this is your spiritual act of worship.
2 Corinthians 2:14
But thanks be to God, who always leads us in triumphal procession in Christ and through us spreads everywhere the fragrance of the knowledge of him.

Is this the "pleasing aroma" He expects from us? To spread the knowledge of Him?

God commanded Moses to take a census of the people and required that each person (20 years old or more) pay a ransom for his life at the time he is counted.  Notice there is no difference in the ransom paid by each person whether rich or poor.  This tells us that no one person is more valuable to God than any other person.

One thing comes through loud and clear in the reading for today.  God is a holy God.
Exodus 29:43
And there I will meet with the Israelites, and the place will be consecrated by my glory.
While we may enjoy the presence of Jesus with us as a friend, we must never lose sight that He is still a holy God.

The two tablets of the Testimony were inscribed by the finger of God! WOW!
