In Isaiah 40:22, it says, "It is He [God] who sits above the circle of the earth..." This shows that the Bible points to a circular, spherical earth. The word in Hebrew translated "circle" is "hug" which means circle or horizon, and since the Hebrews didn't have a word for sphere, they used that one. Now the word hug can mean to embrace, going around the person.
It was because Christopher Columbus was reading Isaiah 40 that he found that allusion that the eatth was round and he wanted to find out if it was right. Then, the world was living under the Ptolemy geocentric model under the name of science.
