'Dreadful' in the Bible

So this is what you have now become to me.When you see something dreadful, you are afraid.

Dreadful sounds fill his ears;when he is at peace, a robber attacks him.

“While I was watching in the night visions, a fourth beast appeared, frightening and dreadful, and incredibly strong, with large iron teeth. It devoured and crushed, and it trampled with its feet whatever was left. It was different from all the beasts before it, and it had 10 horns.

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?
