1 Chronicles - Chapter 6

In this chapter we read about the tribe of Levi.  It is from this tribe that the Levites and priests come. David appointed some of the Levites to minister with music.  There is a list of the Kohathites who were given this role.  These Kohathites were known as the Sons of Korah, and a number of Psalms are attributed to them.  One of these is Psalm 45, which is described as follows:

To the Chief Musician. Set to “The Lilies.” A Contemplation of the sons of Korah. A Song of Love.

This is a Psalm about the Messiah, and verses 6 and 7 are quoted in Hebrews 1, linking them to Jesus.
