First I'd like to state that nowhere in scripture does it state anything about pants, whether being worn by a man, or being worn by a woman. Everyone in the bible as far as we know of wore robes at the time the law found in Deuteronomy was given, and yet many still want to insert the idea of pants into the scripture given.
5 The woman shall not wear that which pertaineth unto a man, neither shall a man put on a woman's garment: for all that do so are abomination unto the Lord thy God.
I have had conversations in which many who claimed breeches worn by the sons of Aaron who were priest, were the same as pants worn today, but lets see what scripture actually says about breeches and how they were described.
And thou shalt make them linen breeches to cover their nakedness; from the loins even unto the thighs they shall reach:
And the priest shall put on his linen garment, and his linen breeches shall he put upon his flesh, and take up the ashes which the fire hath consumed with the burnt offering on the altar, and he shall put them beside the altar.
1.So first we see who the breeches were made for, they were made for the priests of the Most High.
2.The breeches were to worn underneath the garment of the priest
3. The breeches were to be made of linen
4. The breeches were to be made to cover the loins down to the thigh.
This description of breeches sound more like men's boxers worn today underneath the clothing and not like pants.
I once asked a Hebrew male who was constantly spouting off about pants and women who wore pants going to hell, what he thought about a man wearing women's pants. He told me there was no such thing as women pants, and that pants only should be worn by men only.
I then showed him a picture similar to the one I posted above. I asked him what he would say if he saw a man wearing the kind of outfit or pants as in the picture above. Outraged, he stated the man was a homosexual. I asked how could he judge that by what the man was wearing, and he stated in frustration, " Because those are women's pants". The problem is not wearing pants, but cross-dressing which is confusion of genders.
