God described as a shepherd and as a host - both descriptions show God's care of man

I woke up this morning between 1:30 and 2:00 A.M.  So, I've been sitting here browsing through the Bible.  I like the website  http://www.esvbible.org.  There are so many resources to go along with reading.  Also, there is audio to listen to while you read along.  I can close my eyes and listen.

I particularly like Psalms 23 http://www.esvbible.org/search/psalms+23/  If you register, you get all manner of resources.  An example would be that God is described in two ways:  as a shepherd watching over his sheep and as a host who cares for a guest.  

¹ "The Lord is my shepherd; I shall not want. 

       ²He makes me lie down in green pastures.

He leads me beside still waters.

       ³ He restores my soul. 

He leads me in paths of righteousness

        for His name's sake.

  ⁴Even though I walk through the valley of the shadow of death,

        I shall fear no evil,

For you are with me;

       your rod and your staff, 

they comfort me. 

⁵ You prepare a table before me

        in the presence of my enemies;

you anoint my head with oil;

        my cup overflows. 

⁶Surely goodness and mercy shall follow me 

        all the days of my life,

and I shall dwell in the house of the Lord

        forever.
