The soul also includes the intellect or the mind:

"I take from them...that whereupon they set their minds [lit., souls], their sons and their daughters" (Ezek. 24:25).
"With despiteful minds [lit., soul]" (Ezek. 36:5).
"That the soul be without knowledge, it is not good" (Prov. 19:2).
"How long will I bear concern in my soul" (Psa. 13:2).

"Keep sound wisdom and discretion: so shall they be life unto thy soul" (Prov. 3:21-22).

Knowledge, setting of the mind, having in remembrance, etc., are all activities of man's mind, or intellect. The Bible considers all these to be from the soul. The soul includes the human intellect, or the mind.

The soul also includes the emotions:

The soul can love:

"And you shall love Jehovah your God with all your heart and with all your soul" (Deut. 6:5).
"The soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul" (1 Sam. 18:1).
"And you shall exchange the money for anything that your soul desires...or for anything that your soul would like" (Deut. 14:26).
"Whatsoever thy soul desireth" (1 Sam. 20:4).
"My soul longs, indeed even faints,/For the courts of Jehovah" (Psa. 84:2).
"That which your soul pitieth" (Ezek. 24:21).
"So my soul pants/For You" (Psa. 42:1).
"Tell me, O thou whom my soul loveth" (S.S. 1:7).
"My soul desires You in the night" (Isa. 26:9).
"My Beloved in whom My soul has found delight" (Matt. 12:18).
"My soul magnifies the Lord" (Luke 1:46).
"And a sword will pierce through your own soul" (Luke 2:35).

These few verses reveal one function of the soul, which is to love. The desire to love comes from the soul. Hence, human love is a part of the function of the soul.

The soul can hate:

"So that his life abhorreth bread, and his soul dainty meat" (Job 33:20).
"The lame and the blind, that are hated of David's soul" (2 Sam. 5:8).

The soul can be affected in other ways:

These few verses tell us how the soul is affected. The feeling of being affected comes from the soul.

From the above verses we can see the functions in our emotions. Love, hatred, feelings of being affected, sensations, etc., all come from the soul. This shows us that our emotion is also a part of our soul.
