Piety: This word occurs but once in the Authorized Version: "Let them learn first to show piety at home," better "toward their own household" or family. (1 Timothy 5:4) The choice of this word here instead of the more usual equivalents -of "godliness," "reverence," and the like, was probably determined by the special sense of pietas , as "erga parentes," i.e. toward parents.
