2 Samuel 22:48

avengeth me For the wrongs inflicted by Saul (1 Samuel 24:12); for the insults of Nabal (1 Samuel 25:39); for the opposition of those who refused to acknowledge him as king (ch. 2 Samuel 4:8). Vengeance is the prerogative of God (Psalms 94:1), and the visible execution of it was anxiously looked for as His vindication of the righteousness and innocence of His servants.

bringeth down the people under me The reference seems to be, as in 2 Samuel 22:44, to his success in overcoming internal opposition to his rule. It is not the boast of a triumphant despot, but the thanksgiving of a ruler who recognised the vital importance of union for the prosperity of Israel, and the extreme difficulty of reconciling all the discordant elements in the nation, and knew that it was a task beyond his unaided powers. Cp. Psalms 144:2. The Sept. reads "disciplineth."
