Psalms 119:32 - Clarke's commentary and critical notes on the Bible

I will run the way of thy commandments, when thou shalt enlarge my heart. I will run - The particle כי elci, which we translate when, should be translated because: Because thou shalt enlarge, or dilate, my heart; make plain my path by cleansing me from my impurity, and taking the hinderances out of my way. I will then run without dread of stumbling, and every day make sensible progress.
