But Jehovah has been my fortress The Psalmist declares, that great as were the extremities to which he had been reduced, he had found sufficient help in the single protection of God; thus passing a new commendation upon his power, which had been such as alone, and unaided, to put down the mightiest endeavors -- all the force and the fury of his numerous enemies. He does more than say that God was a fortress, where he might hide with safety, and from the top of which he could bid defiance to every assault. Having congratulated himself upon the divine protection, he proceeds to denounce destruction upon his enemies; for it is to be considered as God's special prerogative to make the evil which his enemies devise against his people recoil upon their own heads. The mere defeating, and frustrating their attempts, would afford no inconsiderable display of divine justice; but the judgment of God is far more marvellously manifested when they fall into the pit which they themselves had prepared, when all the subtle plans which they have adopted for ruining the innocent end in their being destroyed by their own craftiness, and when having done their utmost, they fall by their own sword. We are slow to believe that this shall be the issue, and accordingly it is said twice -- he shall cut them off -- the Lord our God shall cut them off It may be noticed also, that the Psalmist in using the expression our God, holds out a ground of encouragement to the faithful, reminding us of what he had said above, that God will not forget his own inheritance, even his people whom he has brought unto the faith of himself.

But the Lord is my defense - In all these purposes of the wicked; in all that they do - whether under the form and sanction of law Psalm 94:20, or by the excitement of passion - my trust is still in God. He is able to interpose in either case, and I may confidently commit my cause to him. On the language used here, as well as the sentiment, see the notes at Psalm 18:2.

The rock of my refuge - Alluding to those natural fortifications among rocks, which are frequent in the land of Judea.

But the Lord is my defence,.... The defence of his church and people, of all the righteous, against those great armies of their enemies that gather together against them: the Targum, in the king's Bible is,
"the Word of the Lord shall be my weapon:''
and my God is the rock of my refuge; to whom recourse is had for shelter from the enemy, and against which the gates of hell cannot prevail: both characters, rock and refuge, agree with Christ, the essential Word of the Lord.

Yet he is safe in God's care.
