Examine me, O Lord,.... His cause, his integrity, and trust in the Lord, as silver and gold are examined by the touchstone, the word of God, which is the standard of faith and practice; and prove me; or "tempt me" (r); as Abraham was tempted by the Lord; and his faith in him, and fear of him, and love to him, were proved to be true and genuine; try my reins and my heart; the thoughts, desires, and affections of it, as gold and silver are tried in the furnace; and so God sometimes tries the faith and patience of his people by afflictive providences; and this examination, probation, and trial, are made by him, not for his own sake, who knows the hearts and ways of all men; but for the sake of others, to make known either to themselves or others the truth of grace that is in them, and the uprightness of their hearts and ways; and it was on this account the psalmist desired to pass under such an examination. (r) "tenta me", Pagninus, Montanus, Junius & Tremellius, &c.
