'Eastern' in the Bible

The princes of Zoan are complete fools;Pharaoh’s wisest advisers give stupid advice!How can you say to Pharaoh,“I am one of the wise,a student of eastern kings”?

I have stirred up one out of the north and he advances, one from the eastern horizon who prays in my name. He steps on rulers as if they were clay, like a potter treading the clay.

“A multitude of camels [from the eastern trading tribes] will cover you [Jerusalem],The young camels of Midian and Ephah;All those from Sheba [who once came to trade] will comeBringing gold and frankincenseAnd proclaiming the praises of the Lord.

“All the flocks of Kedar will be gathered to you [as the eastern pastoral tribes join the trading tribes],The rams of Nebaioth will serve you;They will go up with acceptance [as sacrifices] on My altar,And I will glorify the house of My honor and splendor.
