I find it fascinating that you said that you find all texts outside of the OT and NT as irrelevant, but you decided to use this bit. Not because it is meaningful to you, as you have so eloquently stated, but because you think it will agree with you.
By no means. I used it to show a little known fact to your brother. Even your own people cannot agree. He stated that in no way did "minchah" mean "gift" and this showed he was incorrect. It stated that "minchah" in fact was defined "gift".
 
 But, I will have you notice that it the Sefer HaChinuch didn't say that a Mincha was ONLY a voluntary Korban. It DID, however, say " often comes" as a voluntary Korban.
And, of course, you neglected to read where I posted about my conceding to that fact. I'm more than satisfied that it is used predominately more as a voluntary gift than anything else. I am also so satisfied that these "minchah offerings" were considered so small and inexpensive that it was considered a poor mans offering. And it was so considered this only because he couldn't afford the regular offering. I still do not see something so small and inexpensive being considered in any shape form or fashion a sacrifice.
 
Question ..
 
Where all is it stated that common man, not a priest or prince nor king, was so commanded to bring such a meat offering?
NOW back to the regularly scheduled discussion on Amalek.........
