'Powerful' in the Bible

For a nation has invaded My land,powerful and without number;its teeth are the teeth of a lion,and it has the fangs of a lioness.

It will be a day of dreadful darkness, a day of foreboding storm clouds, like blackness spread over the mountains. It is a huge and powerful army -- there has never been anything like it ever before, and there will not be anything like it for many generations to come!

The Lord raises His voicein the presence of His army.His camp is very large;Those who carry out His command are powerful.Indeed, the Day of the Lord is terrible and dreadful—who can endure it?
