Psalm 23:1-6

Psalms 23:1 The Lord is my shepherd, I shall not be in want. 2 He makes me lie down in green pastures, he leads me beside quiet waters, 3 he restores my soul. He guides me in paths of righteousness for his name's sake. 4 Even though I walk through the valley of the shadow of death, I will 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. 6 Surely goodness and love will follow me all the days of my life, and I will dwell in the house of the Lord forever.
