'Calling' in the Bible

"Make two trumpets of silver. You shall make them of beaten work. You shall use them for the calling of the congregation, and for the journeying of the camps.

Who has worked and done it, calling the generations from the beginning? I, Yahweh, the first, and with the last, I am he."

calling a ravenous bird from the east, the man of my counsel from a far country; yes, I have spoken, I will also bring it to pass; I have purposed, I will also do it.
