'Answered' in the Bible

David went out to meet them, and answered them, "If you have come peaceably to me to help me, my heart shall be knit to you; but if you have come to betray me to my adversaries, since there is no wrong in my hands, may the God of our fathers look thereon, and rebuke it."

David built an altar to Yahweh there, and offered burnt offerings and peace offerings, and called on Yahweh; and he answered him from the sky by fire on the altar of burnt offering.

At that time, when David saw that Yahweh had answered him in the threshing floor of Ornan the Jebusite, then he sacrificed there.
