1:7 All the rivers run into the sea; yet the sea [is] not full; to the place from {f} which the rivers come, there they return again.
(f) The sea which compasses all the earth, fills the veins of it which pour out springs and rivers into the sea again.
1:7 Is not full - So as to overflow the earth. Whereby also he intimates the emptiness of mens minds, notwithstanding all the abundance of creature comforts. Rivers come - Unto the earth in general, from whence they come or flow into the sea, and to which they return by the reflux of the sea. For he seems to speak of the visible and constant motion of the waters, both to the sea and from it, and then to it again in a perpetual reciprocation.
1:4-8 All things change, and never rest. Man, after all his labour, is no nearer finding rest than the sun, the wind, or the current of the river. His soul will find no rest, if he has it not from God. The senses are soon tired, yet still craving what is untried.
