For I have said, Mercy shall be built up for ever: thy faithfulness shalt thou establish in the very heavens.
Ver. 2. For I have said] I believed, therefore have I spoken it; I dare say it shall be so, because thou hast said it (so the Greek here hath it). What God saith we may write upon it, because all the words of his mouth are in righteousness, neither is there anything froward or perverse in them, Proverbs 8:8 .
Mercy shall be built up for ever] Till the topstone be laid, and judgment be brought forth into victory, Matthew 12:20; the sure mercies of David fail not.
Thy faithfulness shalt thou establish in the heavens] Or, with the very heavens; that is, so sure as they are established. If that martyr could say, The heavens shall sooner fall than I will forsake the truth I have learned; how much more may we say so of God's unfailable faithfulness! See Psalms 89:33 .
