'Attackers' in the Bible

Then Samuel took the bottle of oil, and put the oil on his head and gave him a kiss and said, Is not the Lord with the holy oil making you ruler over Israel, his people? and you will have authority over the people of the Lord, and you will make them safe from the hands of their attackers round about them, and this will be the sign for you:

And there was great fear in the tents and in the field and among all the men of the armed force, and the attackers were shaking with fear; even the earth was moved with a great shaking and there was a fear as from God.

And he did great things, and overcame the Amalekites, and made Israel safe from the hands of their attackers.
