“wide open”

1685
"Kent’s hunger for reform and social justice are evident in this print, which combines the biblical with the political. 'Open wide' is used in Psalm 24:9—'Open wide…that the King of Glory may enter in"—as well as in a speech given by President Lyndon B. Johnson, in which he exhorted the audience to 'Open wide the exits from poverty to the children of the poor.'"—http://portlandartmuseum.us/mwebcgi/mweb.exe?request=record;id=29510;type=101
