'Ancient' in the Bible

I'll make sure that you go straight to the Pit, into the lowest part of the earth, where you'll be with people who lived in ancient times. You'll keep company there with the dead, who have gone into the Pit. As a result, your city won't be inhabited. Meanwhile, I will display my glory in the land of the living.

They won't be buried with dead warriors from ancient times, who went straight to Sheol, buried with their war weapons, with their swords placed under their heads and their shields laid on top of their bones, since they spread terror throughout the land of the living.

"This is what the Lord GOD says: "The enemy has been saying about you, "Good! The ancient heights are back in our possession!"'"'
