The Lord is my shepherd; I shall not want.The commentary on this short passage is voluminous, but I will venture a few observations in relation to the central task of this blog: to inquire diligently to know more concerning the kingdom of God.
He maketh me to lie down in green pastures: he leadeth me beside the still waters.
He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake.
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.
Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
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.
As many have observed, this Psalm has two primary metaphors for the Lord. He is a shepherd in verses 1-4 and a host in verses 5-6. The author of the Psalm is presumed to be King David, but we can imagine ourselves as the speaker.
In the first verses, we are sheep, and we are content under the Lord's care. The phrasing of the first verse -- "I shall not want" rather than "I do not want" -- suggests that this contentment is contingent on our willingness to follow the shepherd. Those who follow Him are rewarded with green pastures and still (fresh) waters. We can probably assume that the reference to green pastures and still waters is not a promise of material wealth, but rather a promise of spiritual rest (peace) and wisdom. If we are faithful, our souls will be restored, through repentence and the atonement.
Verse 4 was the focus of our lesson on courage. Even though we follow the Lord ("he leadeth me in the paths of righteousness"), we will encounter trials. But if we are faithful, we will not fear those trials because we will trust in the Lord to protect us. Thus, courage is a function of faith.
In the last two verses, we are prospective guests in the Lord's house. The "house of the Lord" often refers to temples, but given that David was not allowed to build the temple and the fact that the last verse mentions living in the house of the Lord for ever, I suspect this is a more general reference to heaven or the kingdom of God.
The reference to anointing in verse 5 is interesting. Coupled with the reference to a cup running over, the anointing probably was intended to suggest that the Lord is a generous host. But anointing is also done in blessing the sick (perhaps a prelude to our entering into His house is that we become spiritually whole) and to set someone apart for a special calling. For example, Jesus is sometimes referred to as the "anointed" in reference to his special calling as the Christ or Messiah, both of which are derived from words meaning anointed. Thus, the anointing in Psalms 23 could refer to the setting apart of those who enter His kingdom.
Taken as a whole, Psalm 23 is not merely an expression of gratitude for blessings received in this life, but also an invitation to enjoy the blessings of eternal life. In response to Zeezrom's inquiry concerning the kingdom of God, the Psalmist would admonish Zeezrom to become part of the Lord's flock and to follow Him in paths of righteousness.
