For ever, O Lord, thy word, &c.— Or, Thou art for ever, O Lord; thy word, &c. Mudge renders it, Thy word, O Lord, is for ever; firmly fixed in heaven. God's word, and his truth or faithfulness, upon which his laws are founded, are as fixed as the heaven and the earth; for they owe their durableness to the same word and truth.
