Charles H. Spurgeon on Psalms 66:17

With my tongue. Let the praise of God be in thy tongue, under thy tongue, and upon thy tongue, that it may shine before all men, and that they may see that thy heart is good. The fish lucerna has a shining tongue, (A reviewer condemns us for quoting false natural history, but no intelligent reader will be misled thereby. —Editor.) from which it takes its name; and in the depths of the sea the light of its tongue reveals it: if thy heart has a tongue, shining with the praises of God, it will sufficiently show itself of what sort it is. Hence the old saying, "Speak, that I may see thee." Thomas Le Blanc.
