U.S. service members listen to U.S. Navy Capt. Irving Elson, a Jewish Rabbi with 3rd Marine Aircraft Wing, speak during a Passover Seder here, April 7, 2012. Passover commemorates the story of the Exodus, in which the ancient Israelites were freed from slavery in Egypt. The meal was one of the various religious celebrations observed by service members aboard Camp Dwyer over the weekend.
