'Grave' in the Bible

Thus saith the Lord GOD; In the day when he went down to the grave I caused a mourning: I covered the deep for him, and I restrained the floods thereof, and the great waters were stayed: and I caused Lebanon to mourn for him, and all the trees of the field fainted for him.

Whose graves are set in the sides of the pit, and her company is round about her grave: all of them slain, fallen by the sword, which caused terror in the land of the living.

There is Elam and all her multitude round about her grave, all of them slain, fallen by the sword, which are gone down uncircumcised into the nether parts of the earth, which caused their terror in the land of the living; yet have they borne their shame with them that go down to the pit.
