'Power' in the Bible

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

Therefore their inhabitants were of small power, they were dismayed and confounded; they were as the grass of the field, and as the green herb, as the grass on the housetops, and as grain blasted before it is grown up.
