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 - (Psalms 90:1.) In Psalms 31:2 it is "my strong rock," designedly varied by the author, as often elsewhere, when he repeats former psalms.
Whereunto I may continually resort - in every need.
Thou hast given commandment to save me (note, Psalms 44:4; Psalms 68:28) - the basis of the prayer-God's authoritative and efficacious word of promise.
