Mid-17th century. From name + sake. From the phrase "for (one's) name's sake", first found in Bible translations as a rendering of a Hebrew idiom meaning "to protect one's reputation" or possibly "vouched for by one's reputation." A familiar example is in Psalm 23:3, "he leadeth me in the paths of righteousness for his name's sake" (King James Bible, 1604).
