He addeth, "for I have believed Thy commandments," and herein we may justly enquire, why he said not, I obeyed, rather than, I believed. For commandments are one thing, promises another. We undertake to obey commandments, that we may deserve to receive promises.

I have believed that Thou who art God, and who givest unto man whence Thou mayest cause him to do what Thou commandest, hast commanded these things.
