'Security' in the Bible

Now Herod had been in a violent quarrel with the people of Tyre and Sidon. So they came to him as a group. After they had won over Blastus, who oversaw security for the king's sleeping quarters, they asked for a peace agreement because their country depended on the king's country for food.

After giving them a severe beating, they threw them in jail and ordered the jailer to keep them under tight security.
