It is He that sitteth above the circle of the earth, And the inhabitants thereof are as grasshoppers; That stretcheth out the heavens as a curtain, And spreadeth them out as a tent to dwell in;
Rashi on Isaiah
the circle Heb. חוּג, an expression similar to (infra 44:13) “And with a compass (וּבַמְּחוּגָה),” a circle (compas in O.F.).
Ibn Ezra on Isaiah
חוג Circle. Comp. מחוגה compass (44:13), the instrument, which is used to describe a circle.—Here it is stated that the earth is round and not square, though no verse is required for the support of this statement; for it is known by convincing proofs.50This remark is probably made, to shew that the expression from the four corners of the earth used by Isaiah (11:12), and Ezekiel (7:2), is not to be taken literally. He who sitteth upon the circle of the earth. He whose glory fills the whole earth.
Rashi on Isaiah
and whose inhabitants are to Him [lit. before Him] like grasshoppers.
