'Answered' in the Bible

David went out to meet them, and said to them, “If you come peacefully to me to help me, my heart shall be united with you; but if to betray me to my adversaries, since there is no wrong in my hands, may the God of our fathers look on it and decide.”

Then David built an altar to the Lord there and offered burnt offerings and peace offerings. And he called to the Lord and He answered him with fire from heaven on the altar of burnt offering.

At that time, when David saw that the Lord had answered him on the threshing floor of Ornan the Jebusite, he offered sacrifice there.
