Adam Clarke on Psalms 91:1

He that dwelleth in the secret place - The Targum intimates that this is a dialogue between David, Solomon, and Jehovah. Suppose we admit this, - then

David asserts: "He who dwelleth in the secret place of the Most High shall abide under the shadow of the Almighty," Psa 91:1.

Solomon answers: "I will say of the Lord, He is my refuge and my fortress; my God, in him will I trust," Psa 91:2.

David replies, and tells him what blessings he shall receive from God if he abide faithful, Psa 91:3-13.

Then the Supreme Being is introduced, and confirms all that David had spoken concerning Solomon, Psa 91:14-16 : and thus this sacred and instructive dialogue ends.

In the secret place of the Most High - Spoken probably in reference to the Holy of holies. He who enters legitimately there shall be covered with the cloud of God's glory - the protection of the all-sufflcient God. This was the privilege of the high priest only, under the law: but under the new covenant all believers in Christ have boldness to enter tnto the holiest by the blood of Jesus; and those who thus enter are safe from every evil.
