The Scriptures [KJB] rightly teach:
Isaiah 40:22 KJB - It is he that sitteth upon 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:
The word [H2329; chug, khoog] for Circle, means sphere or round [three dimensionally], and is used in Job 22:14 for "circuit" [round]:
Job 22:14 KJB - Thick clouds are a covering to him, that he seeth not; and he walketh in the circuit of heaven.
Its root word is [H2328; chug, khoog] and means compassive [surrounding, around], a circle, thus three dimensionally, a sphere [since the earth is three dimensional physically, not two dimensional. Compare also to [H2287, chagag, khaw-gag] meaning to move around, in a circle, circle, as in the saints compassed the city round about.
Some ask, "Why wasn't the Hebrew word for 'ball' [H1754; in Isaiah 22:18, 29:3; from H1752; Psalms 84:10; see also H1732 [Syriac] Daniel 2:38, 4:1,12,21,35, 6:25, see also H1755; in the KJB 137 times, meaning a 'generation' or revolution of time/space/turning over of persons [new generation]] used, then if it was spherical?" The Hebrew word [H1754] has a depth/range of meaning, which can mean 'ball', like a child's toy [which the earth is not a child's toy] which is thrown about, but it also means to toss about, go in circles, gyrate, wander in a circular pattern, stir around, whirl about, etc.
We can also see the definition of the word
"circuit", the round trip in a year, the heaven being referred to is the appearance in the first heaven [atmosphere]:
Psalms 19:6 KJB - 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.
1 Samuel 7:16 KJB - And he went from year to year in circuit to Bethel, and Gilgal, and Mizpeh, and judged Israel in all those places.
See also the "Coriolis Effect" of the circuit of the winds on a spherical earth -
Ecclesiastes 1:6 KJB - The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.
Hebrews 1:2, 11:3, also speak about the
"worlds", plural, and the transliterated Koine Greek is 'Aeon' [which in chronological sense means time, age, eon, etc, but in the physical/spacial sense, means world, and a world is a sphere, orb].
Hebrews 1:2 KJB - Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
Hebrews 11:3 KJB - Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
This was already seen in the OT, as in
1 Samuel 2:8; Psalms 90:2 KJB, etc in the world for
"world", meaning the earth, and by extension the globe.
1 Samuel 2:8 KJB - He raiseth up the poor out of the dust, and lifteth up the beggar from the dunghill, to set them among princes, and to make them inherit the throne of glory: for the pillars of the earth are the LORD'S, and he hath set the world upon them.
Psalms 90:2 KJB - Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
The moon is also round -
Isaiah 3:18 KJB - In that day the Lord will take away the bravery of their tinkling ornaments about their feet, and their cauls, and their round tires like the moon,
The Rain"bow" is also Round, Bended, Curved, which encircles the atmosphere of the earth, the outer shell when the sun shines upon the Rain.
Genesis 9:13 KJB - I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth.
Genesis 9:14 KJB - And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud:
Genesis 9:16 KJB - And the bow shall be in the cloud; and I will look upon it, that I may remember the everlasting covenant between God and every living creature of all flesh that is upon the earth.
Ezekiel 1:28 KJB - As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spake.
Revelation 4:3 KJB - And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald.
Revelation 10:1 KJB - And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire:
Bended:
Psalms 144:5 KJB - Bow thy heavens, O LORD, and come down: touch the mountains, and they shall smoke.
What about
"corners", as in the
"four corners/quarters" of the earth/land
[Revelation 7:1; Isaiah 11:12; Ezekiel 7:2 KJB]? Corners can mean angle, intersection, but it also means quarters, divisions, North, South, East, West [
Deuteronomy 22:12; 1 Chronicles 9:24; Jeremiah 49:36; Ezekiel 7:2; Revelation 20:8 KJB], and are also found on rounded objects, like a head, which is more spherical:
Leviticus 19:27 KJB - Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard.
There are also natural spheres and circuits [worlds, Sun, moon, stars, atmospheres of air, the eye, blood flow, winds, etc] and spiritual spheres and circuits [of influence, the glory that permeates in all directions from God's presence, atmosphere of grace, all encompassing knowledge of God, the encompassing gospel], as even the things of nature, speaking to us about the Character and things of God:
1 Corinthians 15:46 KJB - Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
