The Lord [is] my shepherd
This is to be understood not of Jehovah the Father, and of his feeding the people of Israel in the wilderness, as the Targum paraphrases it, though the character of a shepherd is sometimes given to him, ( Psalms 77:20 ) ( 80:1 ) ; but of Jehovah the Son, to whom it is most frequently ascribed, ( Genesis 49:24 ) ( Isaiah 40:11 ) ( Ezekiel 34:23 ) ( 37:24 ) ( Zechariah 13:7 ) ( John 10:11 John 10:14 ) ( 1 Peter 2:25 ) ( 5:4 ) . This office he was called and appointed to by his Father, and which through his condescending grace he undertook to execute, and for which he is abundantly qualified; being omniscient, and so knows all his sheep and their maladies, where to find them, what is their case, and what is to be done for them; and being omnipotent, he can do everything proper for them; and having all power in heaven and in earth, can protect, defend, and save them; and all the treasures of wisdom and knowledge being in him, he can guide and direct them in the best manner; wherefore he is called the great shepherd, and the chief shepherd, and the good shepherd. David calls him "my shepherd"; Christ having a right unto him, as he has to all the sheep of God, by virtue of his Father's gift, his own purchase, and the power of his grace; and as owning him as such, and yielding subjection to him, following him as the sheep of Christ do wheresoever he goes; and also as expressing his faith of interest in him, affection for him, and joy because of him: and from thence comfortably concludes,
I shall not want;
not anything, as the Targum and Aben Ezra interpret it; not any temporal good thing, as none of Christ's sheep do, that he in his wisdom sees proper and convenient for them; nor any spiritual good things, since a fulness of them is in him, out of which all their wants are supplied; they cannot want food, for by him they go in and out and find pasture; in him their bread is given them, where they have enough and to spare, and their waters are sure unto them; nor clothing, for he is the Lord their righteousness, and they are clothed with the robe of his righteousness; nor rest, for he is their resting place, in whom they find rest for their souls, and are by him led to waters of rest, as in ( Psalms 23:2 ) : the words may be rendered, "I shall not fail", or "come short" F19; that is, of eternal glory and happiness; for Christ's sheep are in his hands, out of which none can pluck them, and therefore shall not perish, but have everlasting life, ( John 10:27-29 ) .
