I find Psalm 119:32 fascinating. TNIV: “I run in the path of your commands, for you have set my heart free.” JPS: “I eagerly pursue your commandments, for you broaden my understanding.” Hirsch: “I shall walk once again with vigor in the path of thy commandments, if thou wilt ease my heart.”
I see this as the desired answer to the psalmist’s prayer — even if expressed as a hope of what God will do when God quickens the psalmist out of pain and humiliation. The psalmist wants to be able not just to “walk” but to “run” on the path of God’s commandments (the mitsvot).
Freedom, that broad heart of joy and confidence and exhilaration at doing God’s will, is what the psalmist finds. The same idea is found in v. 45: “I will walk about at ease.” Knowing God’s will and doing God’s will liberates the soul — so says the psalmist. It gives that person a heart that is at ease.
