Martyr
Easton's Dictionary
One who bears witness of the truth, and suffers death in the cause of Christ (Acts 22:20; Rev. 2:13; 17:6). In this sense Stephen was the first martyr. The Greek word so rendered in all other cases is translated “witness.” (1.) In a court of justice (Matt. 18:16; 26:65; Acts 6:13; 7:58; Heb. 10:28; 1 Tim. 5:19). (2.) As of one bearing testimony to the truth of what he has seen or known (Luke 24:48; Acts 1:8, 22; Rom. 1:9; 1 Thess. 2:5, 10; 1 John 1:2).
International Standard Bible Encyclopedia
mar'-ter (martus, Aeolic martur): One who gives heed, and so, a "witness," so translated in numerous passages, both as of one bearing testimony, and also as of one who is a spectator of anything (see WITNESS). In the King James Version rendered "martyr" in Ac 22:20, "thy martyr Stephen"; and Re 2:13, "Antipas my faithful martyr"; also 17:6, "the blood of the martyrs of Jesus," where alone the American Standard Revised Version retains "martyrs." These 3 passages are the beginning of the use of the word "martyr" for such witnesses as were faithful even unto death, its uniform modern use.
