die kalte Schulter zeigen

Etymology
lit. 'to show the cold shoulder', which uses the verb used in the first recorded use of the expression, which was in 1816 by Sir Walter Scott in Scots (“The Countess’s dislike didna gang farther at first than just showing o’ the cauld shouther”.) This expression and its German equivalent are mistranslations of  umerum recedentem from the Book of Nehemiah 9.29 from the Vulgate Bible, which actually means "stubbornly they turned their backs on you", which comes from the Septuagint Bible's equivalent. Latin umerus means both "shoulder" and "back".

Verb

 * 1) to give someone the cold shoulder
