The Lord is my shepherd;
there is nothing I lack.
In green pastures he makes me lie down;
to still waters he leads me;
he restores my soul.
He guides me along right paths
for the sake of his name.
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 comfort me.
You set a table before me
in front of my enemies;
You anoint my head with oil;
my cup overflows. Indeed, goodness and mercy will pursue me
all the days of my life;
I will dwell in the house of the Lord
for endless days.
Each day, the shepherd wakes up and covers each of his sheep head's with oil. Sheep are prone to having flies, ticks, and other insects attack them throughout the day. Some of them will even crawl into their ears to the brain and lay eggs in a sheep's brain. This can be so painful the sheep will beat their heads against rocks to ease the pain. How many negative thoughts, lies, and distractions do we allow in our heads before the Lord?
Often this verse is to remind us of the anointing each of us has on our lives. Again, David had been anointed when he became king, similarly, each of us has a call on for our lives. Are we open to accepting that anointing?
