תהילים יז:ה פירוש: רש״י ורד״ק

To support my feet From then on, for every deed of man that I did improperly, may Your eyes see the upright deeds, but my judgment shall go forth from before you.

Maintain: – המוך is an infinitive in the place of an imperative, as "Keep (שמור) the sabbath day" (Deut. 5:12); "Go (הלוך) and call" (Jer. 2:2). And he says:

my treadings in Thy paths: – meaning, my treadings as they go in Thy paths, and in Thy way do Thou maintain.
