suggested the image, "In the shadow of Thy wings will I take refuge." The difference between "fortress" and "high tower" is slight, but the former gives more prominence to the idea of strength, and the latter to that of elevation, both concurring in the same thought as was expressed by "rock," but with the additional suggestion of Jehovah as the home of the soul. Safety, then, comes through communion. Abiding in God is seclusion from danger. "Deliverer" stands last in the first set, saying in plain words what the preceding had put in figures. "My shield and the horn of my salvation" come in the centre of the second set, in obedience to the law of variety in reiteration which the poet's artistic instincts impose. They shift the figure to that of a warrior in actual conflict. The others picture a fugitive from enemies, these a fighter. The shield is a defensive weapon; horns are offensive ones, and the combination suggests that in conflict we are safe by the interposition of God's covering power, and are armed by the same power for striking at the foe. That power ensures salvation, whether in the narrower or wider sense. Thus Jehovah is all the armour and all the refuge of His servant. To trust Him is to have His protection cast around and His power infused for conflict and victory. The end of all life's experience is to reveal Him in these characters, and they have rightly learned its lessons whose song of retrospect begins with "I will love Thee, Jehovah," and pours out at His feet all happy names expressive of His sufficiency and of the singer's rest in possessing Him. Ver. 3 is not a resolution for the future--"I will call; ... so shall I be saved"--but the summing up of experience in a great truth: "I call, ... and I am saved." It unfolds the meaning of the previous names of God, and strikes the key-note for the magnificent sequel.
