My mouth shall shew forth thy righteousness and thy salvation all the day; for I know not the numbers thereof.
My mouth shall show forth thy righteousness and thy salvation all the day. Here he gets from God the assurance of what he had prayed for (Psalms 71:8), "Let my mouth be filled with thy praise and with thy honour all the day;" whence it appears that here the subject of "praise" God's graciously-vouchsafed "salvation;" and God's "honour" is God's "righteousness," or faithfulnes to His promises.
For I know not the numbers thereof - thy favours are innumerable (Psalms 40:5; Psalms 139:17-18; Psalms 36:6).
