(18) Perceived.--Or rather, perhaps, comprehended.

The breadth of the earth.--The earth being conceived of as a vast plain (comp. Job 38:13). Unscientific as all this language is, it is not a little remarkable that the majestic sublimity of it is not one whit affected thereby.

Verse 18. - Hast thou perceived the breadth of the earth? literally, the breadths; i.e. the dimensions generally. The exact dimensions are probably not even yet known. Job can scarcely have had any conception of them. To him the earth was probably a vast plain, extended, he knew not how far, in all directions. Declare if thou knowest it all (comp. vers. 4, 5, and 21).

38:12-24 The Lord questions Job, to convince him of his ignorance, and shame him for his folly in prescribing to God. If we thus try ourselves, we shall soon be brought to own that what we know is nothing in comparison with what we know not. By the tender mercy of our God, the Day-spring from on high has visited us, to give light to those that sit in darkness, whose hearts are turned to it as clay to the seal, 2Co 4:6. God's way in the government of the world is said to be in the sea; this means, that it is hid from us. Let us make sure that the gates of heaven shall be opened to us on the other side of death, and then we need not fear the opening of the gates of death. It is presumptuous for us, who perceive not the breadth of the earth, to dive into the depth of God's counsels. We should neither in the brightest noon count upon perpetual day, nor in the darkest midnight despair of the return of the morning; and this applies to our inward as well as to our outward condition. What folly it is to strive against God! How much is it our interest to seek peace with him, and to keep in his love!Hast thou perceived the breadth of the earth?.... Which may be put for all the dimensions of it, length, breadth, diameter, and circumference, but especially it regards the surface of it, and the measurement of that; hast thou gone over the whole face of the earth and measured it, all its parts, its hills and dales, rocks and mountains, and took a survey of all the cities, towns and villages, woods, forests, fountains, rivers, &c? no; if a man lived as long as Methuselah, and spent all his days in this way, he could never be able to do it; and some parts are inaccessible, and not to be measured by the most skilful geometer;

declare, if thou knowest it all; the whole earth and every part of it, and all that is in it. Whether the other hemisphere and the antipodes were known in Job's time is a question; however not America, or the new world, which is a late discovery; and even now, in our most exact maps of the world, some parts are marked with "terra incognita", the unknown land.
