Isaiah
King James Version (KJV)

“Therefore hell hath enlarged herself, and opened her mouth without measure: and their glory, and their multitude, and their pomp, and he that rejoiceth, shall descend into it.”
King James Version (KJV)
5:14 And he - That spends all his days in mirth and jollity.
Hell enlarged herself after Jesus preached to the Old Testament saints (1Peter 3:18-20) in Abraham's bosom and released them from prison. Before this, a great chasm (Luke 16:19-31) separated Hell (those in torment) from Abraham's bosom. The rich man (in hell) asked that Lazarus (in Abraham's bosom) be sent to dip the end of his finger in water and cool his tongue. Verse 26- the great chasm was fixed... no one could cross/pass over. Jesus released those in prison and Abraham's bosom was emptied, then hell enlarged herself (was expanded).
I believe this is where Catholics get the idea of purgatory (even though this place is not mentioned in the bible). Purgatory was emptied after Jesus descended into hell and released the prisoners from Abraham's bosom.
Is the idea of hell enlarging itself (and being enlarged ever since) the cause of so-called global warming???
