'Deal' in the Bible

Then let our faces be looked on before you, and the face of the youths who eat of the king's dainties; and as you see, deal with your servants.

But out of a shoot from her roots shall one stand up in his place, who shall come to the army, and shall enter into the fortress of the king of the north, and shall deal against them, and shall prevail.

He shall deal with the strongest fortresses by the help of a foreign god: whoever acknowledges [him] he will increase with glory; and he shall cause them to rule over many, and shall divide the land for a price.
