His going forth [is] from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof.
Ver. 6. His going forth is from the end of the heaven] i.e, From the east unto the west, in which course, notwithstanding, while he compasseth the circle of heaven and earth, he visiteth the south and the north, and is unweariable.
And there is nothing hid from the heat thereof] i.e. From the beneft of the sun's heat, who is ut cor incorpore, as the heart in the body, saith Aben Ezra; all things feel the quickening heat of the sun; not only the roots of trees, plants, &c., but metals and minerals, in the bowels of the earth.
