'Enemy' in the Bible

For I was ashamed to ask of the king a band of soldiers and horsemen to help us against the enemy in the way, because we had spoken to the king, saying, "The hand of our God is on all those who seek him, for good; but his power and his wrath is against all those who forsake him."

Then we departed from the river Ahava on the twelfth [day] of the first month, to go to Jerusalem: and the hand of our God was on us, and he delivered us from the hand of the enemy and the bandit by the way.
