The Bible says the earth is spherical

God sits high above the round ball of earth.

Isaiah 40:22 The Message

The Bible Says the Earth is a Globe

Isaiah 40:22

The Message
God sits high above the round ball of earth.
The people look like mere ants.
He stretches out the skies like a canvas—
yes, like a tent canvas to live under.

Peshitta Holy Bible Translated
And him who sits on the sphere of The Earth, and its inhabitants are like grasshoppers; who stretched out the Heavens like a vaulted bowl, and stretched them out as a tent for a dwelling

Douay-Rheims Bible
It is he that sitteth upon the globe of the earth, and the inhabitants thereof are as locusts: he that stretcheth out the heavens as nothing, and spreadeth them out as a tent to dwell in.

Isaiah 10:20-23

The Message

And on that Day also, what’s left of Israel, the straggling survivors of Jacob, will no longer be fascinated by abusive, battering Assyria. They’ll lean on God, The Holy—yes, truly. The ragtag remnant—what’s left of Jacob—will come back to the Strong God. Your people Israel were once like the sand on the seashore, but only a scattered few will return. Destruction is ordered, brimming over with righteousness. For the Master, God-of-the-Angel-Armies, will finish here what he started all over the globe.

Isaiah 23:6-8

The Message

Visit Tarshish, you who live on the seacoast.
Take a good, long look and wail—yes, cry buckets of tears!
Is this the city you remember as energetic and alive,
bustling with activity, this historic old city,
Expanding throughout the globe,
buying and selling all over the world?

Biblical scholars that understand ancient Hebrew and Jewish culture agree the Bible does not say the earth is flat:

The Bible Says the Earth is in Space

Job 26:7

The Message
He spreads the skies over unformed space,
hangs the earth out in empty space.

Contemporary English Version
God, who hung the northern sky and suspended the earth on empty space.

King James Bible
He stretcheth out the north over the empty place, and hangeth the earth upon nothing.

New International Version
He spreads out the northern skies over empty space; he suspends the earth over nothing.

English Standard Version
He stretches out the north over the void and hangs the earth on nothing.
