Psalms 144:2

Now our royal poet multiplies metaphors to extol his God. My goodness, and my fortress. The word for goodness signifies mercy. Whoever we may be, and wherever we may be, we need mercy such as can only be found in the infinite God. It is all of mercy that he is any of the other good things to us, so that this is a highly comprehensive Title — O how truly has the Lord been mercy to many of us in a thousand ways! He is goodness itself, and he has been unbounded goodness to us.

Now our royal poet multiplies metaphors to extol his God. My goodness, and my fortress. The word for goodness signifies mercy. Whoever we may be, and wherever we may be, we need mercy such as can only be found in the infinite God. It is all of mercy that he is any of the other good things to us, so that this is a highly comprehensive Title — O how truly has the Lord been mercy to many of us in a thousand ways! He is goodness itself, and he has been unbounded goodness to us. We have no goodness of our own, but the Lord has become goodness to us. So is he himself also our fortress and safe abode: in him we dwell as behind impregnable ramparts and immovable bastions. We cannot be driven out, or starved out; for our fortress is prepared for a siege; it is stored with abundance of food, and a well of living water is within it. Kings usually think much of their fenced cities, but King David relies upon his God, who is more to him than fortresses could have been. My high tower, and my deliverer. As from a lofty watchtower the believer, trusting in the Lord, looks down upon his enemies. They cannot reach him in his elevated position; he is out of bow shot; he is beyond their scaling ladders; he dwells on high. Nor is this all; for Jehovah is our Deliverer as well as our Defender. These different figures set forth the varied benefits which come to us from our Lord. He is every good thing which we can need for this world or the next. He not only places us out of harm's way full often, but when we must be exposed, he comes to our rescue, he raises the siege, routs the foe, and sets us in joyous liberty. My shield, and he in whom I trust. When the warrior rushes on his adversary, he bears his target upon his arm, and thrusts death aside; thus doth the believer oppose the Lord to the blows of the enemy, and finds himself secure from harm.

Who subdueth my people - Who has once more reduced the nation to a state of loyal obedience. This may refer to the peace after the rebellion of Absalom.

My goodness - Margin, “my mercy.” That is, He shows me mercy or favor. All the favors that I receive come from him. And my fortress; my high tower, and my deliverer - See the notes at Psa 18:2, where the same words occur. My shield - The same word which in Psa 18:2 is rendered “buckler.” See the notes at that passage. And he in whom I trust - The same idea as in Psa 18:2. The tense of the verb only is varied. Who subdueth my people under me - See the notes at Psa 18:47. The language is slightly different, but the idea is the same. It is to be remarked that David “here” refers to his people - “who subdueth my people,” meaning that those over whom God had placed him had been made submissive by the divine power.
