I have pointed this out in all the ancient scriptures JS translated. Even those from Nephi himself. They wouldn't use Greek or understand it. As I mentioned the earliest account (by calendar) of this would be Bro of J to whom Jehovah said, after seeing his finger, that he is "Jesus Christ". A name he never used, at least anciently (i.e. before Greek translation).
IMO the scriptures are not written word-for-word, but have the translators (and their may be many, JS, Mormon, Moroni, several Nephi's, etc...) that recorded via their own best understanding. And JS translated using language we could relate to, not Nephi's real words. BTW, I have stated several times there is not chance in Hades that Nephi recorded on 60# of gold his own diary in is own day in his own words. they didn't have that much gold, i.e. there were only about 40-50 people and most were infighting and they moved numerous times in old and new world settings in one mans lifetime. Hence my continued challenge for those quoting Jacob so word-for-word given his "nation" could not have been 80 people, and his gold and linens, could not have existed at his time.
There are many other examples in scripture, the steel bow, horses in America, etc... that are words we can relate to vs. what was really written. I wouldn't get hung up on it and if you are then you've some how lost the spirit of it all, as NOTHING we are taught is fully and completely accurate. Everything comes second, third, fourth hand, written and lost and rewritten. The true principles will be known by HG all others may or may not touch our senses.
As far as sacrament. The Lord has commanded me personally to take it. I cannot know more than that. However, he never told me how often. This was my challenge during the COVID lockdown. The Lord and I discussed it several times. I know it is of him and is his ordinance. How, why, where and how often, well .... he didn't say that to me, so I will not go into that here. But, if you don't believe it, ok. If you think the spirit is telling you it is wrong.......... we're listening to different spirits.
