Notice in this, and also in the two following Psalms, Messiah having Jehovah for His Shepherd; compare John 10.
I have nothing particular to remark on this Psalm. “Jehovah" is the point; still there is the portion—restoration—security in the shadow of death, in the presence—in spite of enemies, security, and blessing constantly, and to dwell in the house of Jehovah forever. This is personal association with and care of Jehovah in intimacy with Him as a Protector.
This Psalm, then, passing through the trouble, introduces Messiah, as a Man, to the Lord's house—His Father's house. In the following Psalm we have "the earth the Lord's," and the King of Glory in His coming forth. Thus in these two Psalms, Israel's Shepherd in the Person of Christ, i.e., Christ, as the Man united to Israel, owns Jehovah, in its behalf, as in righteousness One with it, as His Shepherd. So He would be baptized—come out of Egypt—obey—though a Son, learn obedience by the things which He suffered. Then also “the earth is Jehovah's, the world and they that dwell therein." This introduces all to Jacob and the hill of the Lord as a center, and who is to sit there? Christ, the King of Glory! And who is He? He is Jehovah—Jehovah of Hosts, mighty in battle, thus identified, in these two Psalms, with the sheep of His pasture—Jehovah, His Shepherd, and manifested as Jehovah in the midst of the assembled world at Zion. What a place, and compass of glory to hold! To us it is the Cross for sin, and death the door, laying down His life for the sheep, and One with the Father; so we may compare our relative positions.
This Psalm is plainly the Lord Jesus Christ, as Man, expressing His faith as Enos. Verse 3 might seem difficult to some, but besides His resurrection, the inquiry into the way in which He entered into the suffering and sorrows of His people will, I suppose, show the force of this, and abundantly fill the hearts of them that know it. The comparison of verses 27 and 32, John 12 and the garden of Gethsemane in John 18:4, will illustrate this.
