'Whistle' in the Bible

And he will raise a signal for a nation from afar, and he will whistle for it from the end of the earth. And look! It comes quickly, swiftly!

And this shall happen: On that day, Yahweh will whistle for the fly that [is] at the end of the stream of Egypt and the bee that [is] in the land of Assyria.

I will whistle to them and gather them, for I have redeemed them, and they will become numerous as they have been numerous [before].
