John Gill Commentary Jeremiah 27:5

"I have made the earth, the men and the beasts that are upon the face of the earth, by my great power and by my outstretched arm; and I give it unto whom it seemeth right unto me." — Jeremiah 27:5 (ASV)

I have made the earth, the man and the beast that [are] upon
the ground
The earth was made by him on the first day, and man and beast on the sixth day, of the creation; the earth is still supported in its being, and man and beast are continued on it in succession: this is mentioned to show his right and authority to dispose of the earth, and all in it, at his pleasure; which is founded on his creation and sustaining of it, and all creatures in it:

which was, and is, as he says, by my great power, and by my outstretched arm; for nothing less could have created the original chaos out of nothing, and brought that into form and order, and produced out of it such creatures as man and beast; and nothing less than that could continue it in being, and a succession of creatures on it:

and have given it unto whom it seemed meet unto me; some part of it to one, and some to another; and more to one than to another; but to none according to their merit, but according to his own sovereign will and pleasure; see (Psalms 115:16) .
