Its a really strange translation. Mia ton sabbaton in Greek is not "one of the sabbaths", but "the first day of the week".
Brother, no translation has understood the "expression" of God: "the first of the Sabbaths". It does not refer to Sunday but to Saturday being the first Sabbath, another way of referring to the seventh day of the creation week. This is necessary because the Sabbath redefined the week in the Promised Land as shown in the OP's first passage quoted. The Sabbath in the Promised Land falls and takes halves between Friday and Saturday, so you only get half of a Friday and half of a Saturday in the Promised Land, with a Sabbath taking halves between those two days, giving us the following order: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Sabbath, and Saturday, the Sabbath being an eighth division in the seven-day week.
How Many Evenings are in a Day?
The "evening" that is not mentioned in the first passage ending the Sabbath in the Promised Land is part of a full 24-hour Saturday, as shown in the first verse quoted where God uses an "expression" that was not previously understood: "the first of the Sabbaths". This "expression" refers to the first Sabbath of creation week or another way of saying the seventh day of the week that we call Saturday. I will use Saturday for the seventh day as different from the Sabbath, which is separate from the seventh day in the Promised Land, to correct the translation of this "expression" of God. Here, "as it downs beyond Saturday" refers to the end of the second half of Saturday, the night half from evening to morning, where Jesus rose on a Saturday night after the Sabbath in the Promised Land and before the morning begins Sunday, as the days of creation are corrected from human tradition since Joshua in Hebrews 3 and 4. In conclusion, the "evening" falls in the middle of the creation days, giving us only one "evening" per creation day.
long after the Sabbath, as it downs beyond Saturday, came Mary Magdalene and the other Mary, to see the tomb. (Mathew 28:1, my own translation)
United in our hope for the soon return of Jesus, Jorge
