What word or phrase does your mother always say?
"a line or band in cloth," 1620s (but probably much older), from Middle Dutch or Middle Low German stripe "stripe, streak," from Proto-Germanic *stripanan (cf. Danish stribe "a striped fabric," German Streifen "stripe"), cognate with Old Irish sriab "stripe," from PIE root *streig- (see strigil). Of soldiers' chevrons, badges, etc., attested from 1827.
"a stroke or lash," mid-15c., probably a special use of stripe (n.1), from the marks left by a lash. Cf. also Dutch strippen "to whip," West Frisian strips, apparently cognate but not attested as early as the English word.
as a punishment were not to exceed forty (Deut. 25:1-3), and hence arose the custom of limiting them to thirty-nine (2 Cor. 11:24). Paul claimed the privilege of a Roman citizen in regard to the infliction of stripes (Acts 16:37, 38; 22:25-29). Our Lord was beaten with stripes (Matt. 27:26).
