Final answer:
The Psalms portray an understanding of humanity as an immaterial soul contained in a material body.
Step-by-step explanation:
In the Psalms, an important book in the Old Testament of the Bible, there is an understanding of humanity as having an immaterial soul contained in a material body. This idea aligns with the concept of dualism, where the soul and the body are seen as separate entities. This is evident in passages such as Psalm 16:9-10, where it says, 'Therefore my heart is glad, and my whole being rejoices; my flesh also dwells secure. For you will not abandon my soul to Sheol, or let your holy one see corruption.' Here, the psalmist acknowledges both the flesh (body) and the soul as distinct elements.
