'Power' in the Bible

but you shall fear Yahweh, who brought you up out of the land of Egypt with great power and with an outstretched arm, and you shall bow yourselves to him, and you shall sacrifice to him.

Therefore their inhabitants were of small power. They were dismayed and confounded. They were like the grass of the field, and like the green herb, like the grass on the housetops, and like grain blasted before it has grown up.
