"A popular etymology of the word zahav argues that it is a contraction of the phrase zeh hav (“give this”) — an allusion to gold’s role as legal tender. This explanation is cited by such luminaries as Peirush HaRokeach, Rabbi Todros Abulafia (1247-1306), Rabbi Binyamin HaRofeh Anav (a brother of the author of Shibbolei HaLeket), the Maharal of Prague (1520-1609), Rabbi Eliezer Papo (1785-1828), and more." https://ohr.edu/8859
