Let my soul live, and it shall praise thee,.... The psalmist desires the continuance of his natural life, not for his own personal advantage, nor for the sake of his family, nor with any worldly, sinister, and selfish views; but for the glory of God, and for the sake of praising him: or his desire is, that his soul might be lively and comfortable; or that he might be in a lively and cheerful frame of spirit, and so be in fit and proper circumstances to praise the Lord; for it is the living man in both senses, natural and spiritual, that is capable of praising the Lord, Isa 38:19; and let thy judgments help me; that is, to praise him: meaning either judgments on his enemies, as Aben Ezra; which furnish out matter and occasion of praise and thanksgiving; see Rev 15:3; or the word of God, the doctrines and precepts of it; see Psa 119:164.
