'Request' in the Bible

At whose request do you come before me, making my house unclean with your feet?

Make a request to the Lord your God for a sign, a sign in the deep places of the underworld, or in the high heavens.

But Ahaz said, I will not put the Lord to the test by making such a request.

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?

I have not given my word in secret, in a place in the underworld; I did not say to the seed of Jacob, Go into a waste land to make request of me: I the Lord say what is true, my word is righteousness.

And before they make their request I will give an answer, and while they are still making prayer to me, I will give ear.
