'Answered' in the Bible

And David went out {to meet them} and answered and said to them, "If you come in peace to me, to help me, {my heart will be joined with you}, but if [you come] to betray me to my adversaries, although [there is] no wrong on my hands, may the God of our fathers see and pass judgment."

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

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