I never actually noticed that Ezekiel 23:19-20 said what it said.
Only after I saw #7 I opened up a bible and leafed through it till I found it.
And to my amazement that exactly what's written in the bible(Although, In a much higher and non understandable language...)
Altrhough #6 isn't exactly accurate...
The jewish scholars said that the clan that Ehud was part of was trained at using swords with both hands
while most of the inhabitants of the ancient world were using only their right arm for sword fighting.
That is why he strapped the sword to his right leg.
He knew the guards would only check the left one.
