Isaiah 14:7

5 The LORD has broken the staff of the wicked, the scepter of the rulers.

6 It struck the peoples in anger with unceasing blows; it subdued the nations in rage with relentless persecution.

All the earth is at peace and at rest; they break out in song.

8 Even the cypresses and cedars of Lebanon exult over you: “Since you have been laid low, no woodcutter comes against us.”

9 Sheol beneath is eager to meet you upon your arrival. It stirs the spirits of the dead to greet you— all the rulers of the earth. It makes all the kings of the nations rise from their thrones.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
