Christians place way too much emphasis upon Paul's "hard to understand" letters:
2Pe 3:15 And count the patience of our Lord as salvation, just as our beloved brother Paul also wrote to you according to the wisdom given him,
2Pe 3:16 as he does in all his letters when he speaks in them of these matters. There are some things in them that are *hard to understand*, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures.
- Paul is NOT our God:
Deu 5:12 Observe the sabbath day, to keep it holy, as Yehovah your God has commanded you.
Eze 20:20 And keep My sabbaths holy, and they shall be a sign between Me and you, that you may know that I am Yehovah your God.
- Acts 20:7 is in context to Paul beginning the counting of the Omer upon the first day of the week "after the Sabbath" following "Unleavened Bread" for the seven Sabbaths leading to the fiftieth Day of Shavuot / Pentecost (Feast of Weeks) as instructed in the Torah.
Act 20:6 but we sailed away from Philippi after the days of *Unleavened Bread*, and in five days we came to them at Troas, where we stayed for seven days.
Act 20:7 *On the first day of the week*, when we were gathered together to break bread, Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight. ...
Act 20:16 For Paul had decided to sail past Ephesus, so that he might not have to spend time in Asia, for he was hastening to be at Jerusalem, if possible, on *the day of Pentecost*.
Lev 23:6 And on the fifteenth day of the same month is the *Feast of Unleavened Bread* to Yehovah; for seven days you shall eat unleavened bread. ...
Lev 23:15 "You shall *count seven full weeks from the day after the Sabbath*, from the day that you brought the sheaf of the wave offering.
Lev 23:16 You shall count fifty days to the day after the seventh Sabbath. Then you shall present a grain offering of new grain to Yehovah.

- In 1 Corinthians Paul was making a collection on the first day of the week because for the Day of Shavuot / Pentecost ("Feast of Weeks") the men are not to arrive in Jerusalem "empty-handed" according to the instructions of the Torah:
1Co 16:2 On the first day of every week, each of you is to put something aside and store it up, as he may prosper, so that there will be no collecting when I come.
1Co 16:3 And when I arrive, I will send those whom you accredit by letter to carry your gift to *Jerusalem*. ...
1Co 16:8 But I will stay in Ephesus until *Pentecost*,
Deu 16:16 "Three times a year all your males shall appear before Yehovah your God at the place that he will choose: at the Feast of Unleavened Bread, at the *Feast of Weeks*, and at the Feast of Booths. They shall not appear before Yehovah *empty-handed*.
