My lips shall utter praise,.... Like water flowing from a fountain, as the word (m) signifies. The heart of a good man is like a fountain of water, abounding: with good things, and his mouth is a well of life; out of the abundance of grace and good things in his heart his mouth speaks, Joh 4:14; and particularly his heart is filled with praise and thankfulness for the many blessings of providence and grace enjoyed; his lips show it forth; it comes flowing from him freely and readily, without force and compulsion, largely and plentifully, constantly and continually, and with great vehemence and strength, as streams from a fountain; when thou hast taught me thy statutes: which is what the psalmist often prays for in this psalm; and signifies he should be very thankful to God for, and should sincerely praise him, could he obtain this favour; see Psa 119:7.
