'Strong' in the Bible

Because I [will be] like a lion to Ephraim and like a fierce strong lion to the house of Judah. I myself will tear and I will go; I will carry off, and there is no one who delivers.

So a great outcry will go up from among your people, and all your strong places will be broken, as Beth-arbel was broken by Shalman in the day of war, as the mother was broken on the rocks with her children.
