Adam Clarke on Psalms 145:1

I will extol thee - I will raise thee on high, I will lift thee up.

I will bless thy name - לעולם ועד leolam vaed, for ever and onward, in this and the coming world. This sort of expressions, which are very difficult to be translated, are on the whole well expressed by those words, in a hymn of Mr. Addison: -

Through all eternity to theeA joyful song I'll raise

But O, eternity's too shortTo utter all thy praise!

This contains a strong hyperbole; but allowable in such cases.
