'Below' in the Bible

“Ask a sign for yourself from the Lord your God [one that will convince you that God has spoken and will keep His word]; make your request as deep as Sheol or as high as heaven.”

“Sheol below is excited about you to meet you when you come [you tyrant of Babylon];It stirs up the spirits of the dead [to greet you], all the leaders of the earth;It raises all the kings of the nations from their thrones [in astonishment at your fall].
