I have given Egypt as your ransom, Cush and Seba in exchange for you

"ransom" could be translated as "a buying back" or "a penalty paid" or "the price paid" to free or buy back people." Yahweh will allow Israel's enemy to conquer these nations instead of Israel.

Seba

This is the name of a nation.
