Matthew Poole and continuators on Psalms 104:8

8 They go up by the mountains: they go down by the valleys unto the place which thou hast founded for them .

In that first division of the Waters from the Earth, some part of them by God's command contrary to their own nature went upwards and became Springs in the Mountains, and the greatest part went downwards to the Chanels made for them. Others, both antient and later Interpreters, read the words thus, The Mountains ascend, the Valleys descend, when the Waters were separated, part of the Earth went upward and made the Mountains, and part went downward and made the Valleys or low Grounds. But our Translation seems the best, as being most agreeable to the Context, because he speaks of the Waters both in the foregoing and following Verses.

Unto their proper Chanels and Receptacles which God provided for them.

Marginal references: Or, the [illegible: 1+ letters] tains asc[illegible: 1+ letters]d, the valleys descend.
