Psalm 23 relies on the imagery of a shepherd and sheep, as does Jesus's parable of the lost sheep.

I believe this is psalm beginning with The Lord is my shepherd. The imagery presents God as a sephard of men leading them both through life and death. The speaker is the sheep and the Lord guides his sheep through all troubles and gives him refuge:

Surely your goodness and love will follow me all the days of my life, and I will dwell in the house of the Lord forever.
