Psalms 23 1-6 “The Lord is my shepherd; I shall not want. 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.
The Amplified Bible Psalms 23 as, “ The Lord is my Shepherd [to feed, to guide and to shield me], I shall not want”. To “not want,” or to “lack nothing,” is a result of God being our Shepherd, Who loves us, cares for us, and provides for us.
Want comes from the Hebrew word “chacer”
meaning-to lack, lessen, be abated, bereaved, decrease, (cause to) fail, (have) lack, make lower.
David is stating that because God is his Shepherd, he will not lack or have want of anything; he will not decrease or become bereaved; God will not fail him as the Good Shepherd. God will uphold him and keep him from diminishing to a lowly state. David is proclaiming his faith in God as his Shepherd to provide for all of his needs; he has all he could ever want because he trusts in God, and his God will never fail him.
David tells us in Psalms 37:25 “I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed begging for bread.”
