As we begin our discussion of round earth versus flat earth, one text is used to declare that the earth is disk-like rather than spheroidal. Let’s take a look:

Yesha`yahu (Isaiah) 40:22
It is he that sits upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretches out the heavens as a curtain, and spreads them out as a tent to dwell in:

As we can see from this passage, the earth is a circle, and the heavens are a curtain.  Right?

Let’s see what the Hebrew has to say:

The word interpreted as circle is the word choog (חוּג) (Strong’s 2329), which is interpreted as a circle, or a circuit, or a compass.

Let’s take a look at some of the synonyms for circle: ring, loop, round, sphere, disk.

Synonyms for circuit: tour, trip, journey, route, course.

Synonyms for compass:  scope, range, area, extent, breadth 

Synonyms for orbit: path, track, trajectory, revolution, circle

Now, let’s take a look at the word for curtain.  In the Hebrew, the word in this passage is doq (דֹּק) (Strong's H1852), which is typically translated into the English as something crumbling, i.e. fine (as a thin cloth).  In the last instance, it is also interpreted as a curtain. However, if we look at the root for doq, we find the word daqaq (דָּקַק) (Strong's H1854. (dâqaq).  We see that the word doq in the first instance means something crumbling, and we see now that its root daqaq means to crumble, to make dust, to make into powder. 

So, at this point, this passage could easily read as follows:

Yesha’yahu (Isaiah) 40:22
It is he that sits upon the orbit of the earth, and the inhabitants thereof are as locusts; that stretches out the heavens as a crumbling powder, and spreads them out as a tent to dwell in:

Finally, let’s review the last word for tent.  In the Hebrew, the word is ohel (אֹהֶל) (Strong's H168) which is generally interpreted as a tent, but also means a covering, a dwelling place, a home, or even a tabernacle. Let’s use tabernacle instead of tent in this instance:

Yesha’yahu (Isaiah) 40:22
It is he that sits upon the orbit of the earth, and the inhabitants thereof are as locusts; that stretches out the heavens like a crumbling powder, and spreads them out as a tabernacle in which to dwell:

This passage then can readily be understood as consistent with our current cosmology; a cosmology that contemplates a heliocentric solar system and stars spread out in the heavens like a crumbling powder.
