'Sky' in the Bible

David looked up and saw the Lord's messenger standing between the earth and sky with his sword drawn and in his hand, stretched out over Jerusalem. David and the leaders, covered with sackcloth, threw themselves down with their faces to the ground.

David built there an altar to the Lord and offered burnt sacrifices and peace offerings. He called out to the Lord, and the Lord responded by sending fire from the sky and consuming the burnt sacrifice on the altar.

David did not count the males twenty years old and under, for the Lord had promised to make Israel as numerous as the stars in the sky.

O Lord, you are great, mighty, majestic, magnificent, glorious, and sovereign over all the sky and earth! You have dominion and exalt yourself as the ruler of all.
