The answer is Jacob in Gen 32.
Laura states <<I looked all over but couldn't find it>>
Well the following juxtaposition of verses may help:
Gen 32:24 And a MAN wrestled with him...
Gen 32:28 ..for you have fought with ANGELS and men...
Gen 32:30 ..for I have seen an ANGEL face to face
The same Hebrew word can be used for Judge, Angel and G-d--however a scribe
when writing the word in the Torah scroll must only have a proper intention
if the word refers to G-d himself and not if it refers to a Judge or Angel.
Hope this helps.
