Is the Bible too Bizarre for Worship?

Question

It talks of unicorns

[Isaiah 34:7] "And the unicorns shall come down with them, and the bullocks with the bulls; and their land shall be soaked with blood, and their dust made fat with fatness."

And that the earth is flat/ rectangular

[Isaiah 11:12] "And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth."

And this one I'm not even gonna explain...

[Deuteronomy 23:1 ESV]"No one whose testicles are crushed or whose male organ is cut off shall enter the assembly of the Lord."

Answer 1

Isaiah 34:7 The wild oxen shall come down

Four corners - north, south, east and west

He who is emasculated by crushing or mutilation - got me on that one, but I didn't make the rules, he did

Answer 2

No

And the bible does not say that the earth is a flat rectangle

Isaiah 40:22
"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:"(KJ)

Keep in mind that was written well before people ever found that out.

Here's the first text you mention but in a different translation.

"Wild oxen will also fall with them and young bulls with strong ones; Thus there land will be soaked with blood, and there dust becomes greasy with fat."(New American Standard Bible: Updated Edition.)

I'll explain this since it's the only text you mention that is actually difficult to understand.If you read the chapter you know it's talking about God punishing nations, in this case Edom.
The animals mentioned are the important people of Edom who's blood will cover the country.
Of course that already happened since it's no longer around.

"gather together the dispersed of Judah from the four corners of the earth."
That's an expression it doesn't mean the earth is flat and that should be obvious to anyone.

Ma poster below said:

Fine, I'll explain it. Eunuchs weren't allowed to worship in God's temple. Reproduction was really important to the Israelites.
First they hopped to be the ones who led to the Messiah.
Second God promised Abraham that his decedents would grow to be many.
Finally certain positions in the temple could only be held by certain families.
Before anybody says anything about the eunuch mentioned in the Greek scriptures I'll clarify that he was a eunuch only in rank.
Eunuchs were trusted people b/c they couldn't sleep with the wives of Kings or other high ranking women. Therefor someone who had a high rank could be called a eunuch to show this and the fact there trusted.
However the Israelites were opposed to creating eunuchs the way other civilizations would. I.E. crushing there testicles or cutting there penis.
