He accepted as true what the prophet Moses wrote down in Genesis 2:7-14:

And the name of the third river is Tigris: the same passeth along by the Assyrians. And the fourth river is Euphrates.”​—Douay Version of the Bible.

13. What ancestors of Jesus were exiles between those two rivers, but why was Paradise not then existing in that general area?

¹³ As regards the rivers Tigris and Euphrates, human ancestors of Jesus Christ, namely, Shealtiel and Zerubbabel (whose name means “Seed of Babel [or, Babylon]”), had been exiles for many years in the Mesopotamian valley that lies between those two rivers. That was during the years 607 to 537 before our Common Era. (Luke 3:23-27; Matthew 1:1, 12-16) But at that time the original Paradise of Pleasure was not in existence, in that neighborhood of the Tigris and Euphrates Rivers.
