'Strong' in the Bible

He is to keep himself from wine and strong drink, and take no mixed wine or strong drink or any drink made from grapes, or any grapes, green or dry.

And see what the land is like; and if the people living in it are strong or feeble, small or great in number;

But the people living in the land are strong, and the towns are walled and very great; further, we saw the children of Anak there.

So the makers of wise sayings say, Come to Heshbon, building up the town of Sihon and making it strong:

Come now, in answer to my prayer, and put a curse on this people, for they are greater than I: and then I may be strong enough to overcome them and send them out of the land: for it is clear that good comes to him who has your blessing, but he on whom you put your curse is cursed.

And looking on the Kenites he went on with his story and said, Strong is your living-place, and your secret place is safe in the rock.
