The idiomatic expression was possibly originated in Aesop’s Fables, or the Aesopica, a compilation of moral stories attributed to Aesop, a slave and narrator supposed to have lived in ancient Greece between 620 and 564.

The phrase entered the English language in the first half of the 17th century. It has been reiterated by many authors, most often telling a person who could not be trusted. William Chillingworth writes it: “These men can blow hot and cold out of the same mouth to serve several purposes” (The Religion of Protestants, 1638).
