'Mighty' in the Bible

For Jehovah your God is the God of gods, and the Lord of lords, the great God, the mighty and the terrible, who regardeth not persons, nor taketh reward;

And thou shalt speak and say before Jehovah thy God, A perishing Aramean was my father, and he went down to Egypt with a few, and sojourned there, and became there a nation, great, mighty, and populous.

and according to all that mighty hand; and according to all the great terribleness that Moses had wrought in the sight of all Israel.
