'Cloud' in the Bible

And when the players on horns, and those who made melody in song, with one voice were sounding the praise and glory of the Lord; with loud voices and with wind instruments, and brass and corded instruments of music, praising the Lord and saying, He is good; his mercy is unchanging for ever: then the house was full of the cloud of the glory of the Lord,

So that the priests were not able to keep their places to do their work because of the cloud; for the house of God was full of the glory of the Lord.
