EZK 6:13

13 Then shall ye know that I am Hashem, when their slain shall be among their gillulim all around their mizbechot, upon every givah ramah [(high hill)], in all the tops of the harim, and under every spreading tree, and under every leafy elah [(oak tree)], the makom [(place)] where they did offer rei'ach nicho'ach to all their gillulim.
