'Someone' in the Bible

Go west across the sea to the coasts of Cyprus and see. Send someone east to Kedar and have them look carefully. See if such a thing as this has ever happened:

Why should you be like someone who is helpless, like a champion who cannot save anyone? You are indeed with us, and we belong to you. Do not abandon us!"

This man, Jeconiah, will be like a broken pot someone threw away. He will be like a clay vessel that no one wants. Why will he and his children be forced into exile? Why will they be thrown out into a country they know nothing about?

Nor will the Levitical priests ever lack someone to stand before me and continually offer up burnt offerings, sacrifice cereal offerings, and offer the other sacrifices."'"
