That I may publish with the voice of thanksgiving, and tell of all thy wondrous works.
That I may ... wondrous works - in having so marvelously delivered me. So Israel made known God's wonders performed in her deliverance at the Red Sea (Exodus 14:1-31; Exodus 15:1-27), and shall again do so on the occasion of a still greater and a final deliverance (Isaiah 63:7). He whose heart is so full of God's goodness that his lips cannot but proclaim it, is in the fittest frame for fresh manifestations of God's grace being vouchsafed, which in turn shall call forth fresh praises.
