'Answered' in the Bible

Joab said, “May the Lord add to His people a hundred times as many as they are! But, my lord the king, are they not all my lord’s servants? Why then does my lord require this? Why will he bring guilt on Israel?”

Then David built an altar to the Lord there and presented burnt offerings and peace offerings. And he called on 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 sacrificed there.
