The earth. — i.e., the cultivated and enclosed part of it.
The fields. — The open country.
The highest part of the dust of the world. Literally, “the head of the dusts of the fertile earth” i.e. the heaps of the clods of arable land, or better perhaps, “the sum of the atoms of dust.” Some refer to Genesis 2:7, and interpret the words of man, as formed out of the dust.
