My zeal hath consumed me— See Psalms 69:9. "My zeal towards thy law, which my enemies violate and contemn." The original of very pure, in the next verse, is, tried in the fire; an allusion to metals, which are perfectly refined in the furnace and purified from all dross. Thus, in a spiritual sense, God's word is very pure; i.e. perfectly good, without any mixture of error, or indulgence of vice.
