Be thou my strong habitation, whereunto I may continually resort: thou hast given commandment to save me; for thou art my rock and my fortress. Be thou my strong habitation - Instead of מען maon, habitation, many of Kennicott's and De Rossi's MSS. read מעז maoz, munition or defense. Be thou my rock of defense.
Thou hast given commandment to save me - Thou hast determined my escape, and hast ordered thy angels to guard me. See Psalms 91:11, Psalms 91:12.
