He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.

Without a Title, as are all the Psalms in Book IV, except 90, 101, 103. See notes on p. 809. If by Moses, then the "I" of the members (Psalms 91:2 ), and (Psalms 91:9 -), may be Joshua, a type of Messiah. Compare Deuteronomy 1:38 ; Deuteronomy 3:28 ; Deuteronomy 31:7 , Deuteronomy 31:23 . If Moses were the author (this Psalm following his), then all the Scriptures quoted in Matthew 4 were from his writings. Note the references to Deuteronomy 32:1-14 . It is not David's, for we have no more right to insert the name of "David" where it is not written, than to take it out where it is.

9.

Because thou hast made the LORD, which is my refuge, even the most High, thy habitation;

Because Thou, &c. Hebrew reads "For thou, O LORD, [art] my refuge. "The change of person marks the Structure, and is not due to "textual corruption".
