The original language is proof enough that either gate or door is applicable. You can argue until the cows come home, but that doesn't change anything. It just reveals a stubborn spirit.
One verse then does not prove anything.
But the use of a word in scripture or verse is defined by 'all' of scripture not with itself as in just the one verse.
a number of verses of scriptures has been given which I will search out and will get back on in reply one way or the other either by answers or more questions .
bare with me in patience please.
