Captain

Heb. sar (1 Sam. 22:2; 2 Sam. 23:19). Rendered “chief,” Gen. 40:2; 41:9; rendered also “prince,” Dan. 1:7; “ruler,” Judg. 9:30; “governor,’ 1 Kings 22:26. This same Hebrew word denotes a military captain (Ex. 18:21; 2 Kings 1:9; Deut. 1:15; 1 Sam. 18:13, etc.), the “captain of the body-guard” (Gen. 37:36; 39:1; 41:10; Jer. 40:1), or, as the word may be rendered, “chief of the executioners” (marg.). The officers of the king’s body-guard frequently acted as executioners. Nebuzar-adan (Jer. 39:13) and Arioch (Dan. 2:14) held this office in Babylon.

The “captain of the guard” mentioned in Acts 28:16 was the Praetorian prefect, the commander of the Praetorian troops.
