What does Isaiah 14:15 mean?

John Gill's Exposition of the Bible
Isaiah 14:15

Yet thou shalt be brought down to hell
Into a very low and miserable condition; see ( Matthew 11:23 ) instead of ascending to heaven: or "to the grave"; though, inasmuch as afterwards a burial is denied him, the word may be taken for the infernal pit, and so is, as much as can be, opposed to heaven; and this will be true of antichrist, when the beast and false prophet will be cast alive into the lake of fire, ( Revelation 19:20 ) : to the sides of the pit;
instead of being on the mount of the congregation in the sides of the north; another word for hell, the pit of corruption, and the bottomless pit. The Targum is,

``to the ends of the lake of the house of perdition;''
the place of everlasting destruction.
