'Terrible' in the Bible

They piled them in countless heaps, and there was a terrible odor in the land.

then the hand of the Lord will surely bring a very terrible plague on your livestock in the field, on the horses, the donkeys, the camels, the herds, and the flocks.

And he said, Behold, I make a covenant: before all thy people I will do marvels, such as have not been done in all the earth, nor in any nation: and all the people among which thou art shall see the work of the LORD: for it is a terrible thing that I will do with thee.
