Leviticus 8:36 New International Version (NIV)
36 So Aaron and his sons did everything the Lord commanded through Moses.
Aaron and his sons did everything that the Lord commanded. There were many detailed lists, and this was remarkable. They worked to learn and do what God wanted. They had an attitude to carry out every detail. This is a good model to follow when learning to follow God. It is important to be thoroughly holy. Do not be a rough approximate. Practice and have a true attitude to learning who God is and who he wants you to be.
