Matthew Henry Presbyterian @wholebiblehenry

Here is, I. An account of four things that are unsearchable, too wonderful to be fully known. And here, 1. The first three are natural things, and are only designed as comparisons for the illustration of the last. We cannot trace, (1.) An eagle in the air.

John Gill Reformed Baptist @doctorgill

For three things the earth is disquieted,.... The inhabitants of it are made very uneasy; and for four which it cannot bear; they are a load and burden upon it, and are intolerable to those that dwell on it, and make them very uncomfortable.
