'Heaven' in the Bible

And David lifted up his eyes, and saw the angel of the LORD stand between the earth and the heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders of Israel, who were clothed in sackcloth, fell upon their faces.

And David built there an altar unto the LORD, and offered burnt offerings and peace offerings, and called upon the LORD; and he answered him from heaven by fire upon the altar of burnt offering.

David didn’t count the men aged 20 or under, for the Lord had said He would make Israel as numerous as the stars of heaven.

Thine, O LORD, is the greatness, and the power, and the glory, and the victory, and the majesty: for all that is in the heaven and in the earth is thine; thine is the kingdom, O LORD, and thou art exalted as head above all.
