1 Chronicles 6 God’s memory is perfect and He is a rewarder to the faithful.

In the Levitical priesthood there is a a great reward to the line of Zadok who came through the line of Aaron. Zadok was rewarded because he was faithful to David and in doing so was faithful to God.

In the future millennium there will be a third temple and Zadok’s line will receive the privilege of priesthood over that temple.

God remembers and God is a rewarder to the faithful.
