2,000 years of Tradition is tough. So, I'll be blunt. None of what you ask matters. Justin clearly added the word that is translated "almost". If it didn't matter, he wouldn't have said it. But he did in order to adhere to his Tradition. If he adhered to the Tradition from Christ to the apostles to the bishops in Asia Minor Polycarp, Melito, and Polycrates, he would not have had to add to Scripture.
But, in the quote from your post, you seemed to say that Justin stated that Moses hands were outstretched "almost until" evening; yet the quote from Justin did not state that. The almost (whatever it was in the original language in which Justin wrote) was referring to the crucifixion, not Moses. So I am confused by what you mean. And again, the translation says "almost"; what does the original say ?
If scripture says Jesus died at 3pm, Justin says almost 3pm. If scripture says on the cross until sunset, Justin says almost until sunset.
Evening/opsios is from 3 pm til sunset. Here again I am confused; I quoted the verses (including John, apparently from whom Polycarp got his information) - they all say finished at 3 (9th hour). The 9th hour is the beginning of the time period opsios. I then referenced passages in the Gospel where (in a single event account) opsios is used for the full range of time (3 pm - sunset). After sunset is niktos and the time is recorded in "watches" (1st, 2cnd, 3rd, and 4th watch) - as in the Gospel account referenced.
Here's NT:
Mk. 1:32 And at even, when the sun did set, they brought unto him all that were diseased, and them that were possessed with devils.
Yup, as I said the particular portion of opsios/opsias (as in the scriptures I referenced) is given a further description where a particular portion of opsios is meant.
That was Mark agreeing with the OT definition of evening.
Take a look at John 6:16-17, opsios is used in both verses and covers a span of time. The second mention, later on chronologically, opsios is described as now dark.
Then, in Matthew:
14:15 - 23 ( a long span of time) opsios is used in verse 15 and again in verse 23 [this is the account of feeding the 5,000]. Then, note that when nightime (niktos) is referenced in verse 25, the time is recorded by "watches" (here the fourth watch).
Mk. 14:17 And in the evening he cometh with the twelve. (to eat Passover. arrested at midnight. tried in the morning. crucified and dies at 3pm).
So which part of the opsias (aprox. 6 hours) is meant here ?
Hands up until sunset, so a new day has begun from Thurs Passover to Friday preparation/high sabbath.
But again, the "hours" refer to the daytime, the "watches" to the nightime.
(The twelfth hour is 6 pm til sundown; opsios/opsias covers the 9th through twelfth hour. The watches start at sundown and end with the ending of the 4th watch at sunrise; midnight is the 3rd watch). So, I am having a difficulty following what exactly your count is.
Mk. 15:42 And now when the even was come, because it was the preparation, that is, the day before the sabbath, (Joseph requests body, Pilate has to make sure He is dead, grants body, Joseph and Nicodemus prepare it, and bury it.)
This is opsios again; a six hour span which is not further narrowed to which part of opsios. (See Matthean pasages and those form John, above, for the narrowing applied to the span called opsios.)
Matthew (27):
opsios again, no narrowing
Luke 23:54
Joseph requests the body and entombs on the day of preparation as sabbath (beginning of sabbath) is coming on.
John 19: 42
entombment on paraskeui (nearing the sabbath, ie sunset)
Christ died on the cross at 3pm Thursday. His hands were up until sunset at 6pm. That is three hours. Thursday ends now and Friday begins (a Jewish day changes at sunset). Joseph requests body. 1st watch is 3 hours later. Total is maximum 6 hours from death to burial.
I'm sorry, I don't understand how you derive this. I hope the above will help to explain at least why I don't understand what you mean.
Just to clarify:
opsios/opsias - 3 pm until sundown (9th hour until twelfth hour)
Do you mean that Josephus requests the body at our time after 6 pm (after the twelfth hour, during the first watch) ?
How does this correlate with the testimony in the Gospel of John (entombment on preparation/pareskeui as sabbath is nearing)
and the Gospel of Luke (entombment on preparation/paraskeui, when sabbath is nearing) ?
