'Uttermost' in the Bible

It will happen in that day that Yahweh will whistle for the fly that is in the uttermost part of the rivers of Egypt, and for the bee that is in the land of Assyria.

They come from a far country, from the uttermost part of heaven, even Yahweh, and the weapons of his indignation, to destroy the whole land.

From the uttermost part of the earth have we heard songs. Glory to the righteous! But I said, "I pine away! I pine away! woe is me!" The treacherous have dealt treacherously. Yes, the treacherous have dealt very treacherously.
