2 Samuel - Chapter 22
This chapter is a song of praise by David - which is also recorded in the Bible as Psalm 18.
In this Psalm there are many descriptions of God which apply to Jesus:
my rock
my fortress
my deliverer
my refuge
the word of the Lord
Saviour
The description I have picked is in verse 29:
“For You are my lamp, O Lord;
The Lord shall enlighten my darkness."
This is the description of Jesus that John uses at the start of his Gospel:
In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.
