A promise given to us that HE will be with us
Psalm 23 King James Version (KJV)
23 The Lord is my shepherd; I shall not want.
2 He maketh me to lie down in green pastures: he leadeth me beside the still waters.
3 He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake.
4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever.

When I think of this Psalm I read it in a personal ‘1st person’ towards me version.
The Lord is MY shepherd. I shall not want.
(meaning I need nothing else since I have a shepherd to look after me. In the old country a shepherd watched the sheep for hours and hours risking his own life for their safety.)
He maketh me to lie down in green pastures:
(He wants me rested and not weary, and green grass tends to be soft.)
He leadeth me beside still waters.
(bringing refreshment to my spirit and coolness to my parched way)
He restoreth my soul.
(He helps me to feel new and revived.)
He leadeth me in the paths of righteousness for his name’s sake.
(He keeps me going in the right path, the right direction as I follow him.)
Yea, though I walk through the valley of the shadow of death.
(When I was diagnosed with cancer. It was not scary but it did make me think)
I will fear no evil: for thou are with me
(there is safety in knowing evil cannot take His love away from me and I am not alone.)
Thy rod and they staff they comfort me.
(when I walk in the trails I often will take a walking stick to balance me and keep me safe; it is in the knowing that it is a help to me.)
Thou prepares a table before me in the presence of mine enemies.
(He provides food for endurance and strength so I can go forward.)
Thou anointest my head with oil; my cup runneth over
(It is like a healing balm, oil for protection and health; He gives me more than I need)
Surely goodness and mercy shall follow me
(comforters, helpers to walk alongside me)
All the days of my life
(I am not ever alone. No matter how I feel)
and I will dwell in the house of the Lord for ever
(what a wonderful promise to be given to us, in the house as family, with our father)Amen and Amen
A promise given to us that HE will be with us no matter what.
