Guard ( 1.) Heb. tabbah ( properly a " cook," and in a secondary sense " executioner," because this office fell to the lot of the cook in Eastern countries), the bodyguard of the kings of Egypt ( Gen. 37: 36) and Babylon ( 2 Kings 25: 8; Jer. 40: 1; Dan. 2: 14). ( 2.) Heb. rats, properly a " courier," one whose office was to run before the king' s chariot ( 2 Sam. 15: 1; 1 Kings 1: 5). The couriers were also military guards ( 1 Sam. 22: 17; 2 Kings 10: 25). They were probably the same who under David were called Pelethites ( 1 Kings 14: 27; 2 Sam. 15: 1). ( 3.) Heb. mishmereth, one who watches ( Neh. 4: 22), or a watch- station ( 7: 3; 12: 9; Job 7: 12). In the New Testament ( Mark 6: 27) the Authorized Version renders the Greek _spekulator_ by " executioner," earlier English versions by " hangman," the Revised Version by " soldier of his guard." The word properly means a " pikeman" or " halberdier," of whom the bodyguard of kings and princes was composed. In Matt. 27: 65, 66; 28: 11, the Authorized Version renders the Greek _kustodia_ by " watch," and the Revised Version by " guard," the Roman guard, which consisted of four soldiers, who were relieved every three hours ( Acts 12: 4). The " captain of the guard" mentioned Acts 28: 16 was the commander of the Praetorian troops, whose duty it was to receive and take charge of all prisoners from the provinces.
