'Bird like' in the Bible

And when they say to you, Make request for us to those who have control of spirits, and to those wise in secret arts, who make hollow bird-like sounds; is it not right for a people to make request to their gods, to make request for the living to the dead?

And you will be made low, and your voice will come out of the earth, and your words will be low out of the dust; and your voice will come out of the earth like that of a spirit, making bird-like noises out of the dust.
