My mouth shall speak the praise of the Lord,.... Always, at all times, as long as he lived; and particularly when all the Lord's people shall be brought safe to glory, and the wicked destroyed; when, as Kimchi observes, he should live again with the dead that shall be raised;and let all flesh bless his holy name for ever and ever; not every animal, or irrational creature; not carnal men, but spiritual men; such as are praying ones, that come to a God hearing prayer: these should be praising ones; such who have hearts of flesh given them, and are sensible of divine favours, as well as of their sinfulness and unworthiness; Jews and Gentiles, all sorts of men called by grace, all flesh on whom the Spirit of God is poured; these are all excited to praise and bless the holy name of the Redeemer, with the words and by the example of the psalmist.
And thus the psalm ends as it begun, with praise and blessing.
