I'm not sure if you are aware that there are such things as syntax and idiom.
If you put preposition 'LE' in front of (EYNEY ['eyes'], you get the idiom
'in front of' or 'in the sight of'.
En Mishpat does not have preposition LE in front of it. It is a toponym,
referring to a geographical feature, namely a spring.
Ergo, your reasoning is faulty and not in step with plain Hebrew idiom.
Meaning comes from words connected to other words, not from words in
isolation from each other.
You've stated your case. You've been answered by many. Your reasoning is
poor. Time to drop it.
