3 Leviticus 23:8 |
| Naphtali | First Fruits | by observation |
3 Leviticus 23:9-10 |
| Manasseh | New Grain | 50 days later |
3 Leviticus 23:15-16 |
| Simeon | Trumpets | 7/1 |
3 Leviticus 23:23-24 |

| Issachar | Tabernacles | 7/15 |
3 Leviticus 23:33-34 |
| Zebulun | Tabernacles | 7/22 |
3 Leviticus 23:36 |

There are several decisions being made for this grid to come out as it is. First, there are only 12 holidays a year, so Dan ends up with the weekly Sabbath instead of an annual holiday. This works, however, as each tribe also gets a New Month/Month for the year, including Dan, though only on leap years that contain a 13th month, such as the 7th and 50th years. When you realize that every tribe has a month in the year and thus a New Month holiday, and every tribe, except Dan, has an annual holiday, the only holiday left is the weekly Sabbath, which MUST grid to Dan.
In order to get 12 holidays in a year several tribes share a holiday. Gad and Asher share Unleavened Bread. This makes plenty of sense though as there is both an "opening assembly" and "closing assembly" that book-end the week-long meeting. In the same way Issachar and Zebulun share Tabernacles later in the year.
Another thing that's going on to arrive at 12 holidays is to give Judah "Selection Day" on the tenth day of the first month. This is the day you "select" the lamb for Passover on the fourteenth, and it appears to be a legitimate day in and off itself and fits nicely with Judah (which we'll explore below).
The third and last decision causing there to be 12 holidays in the year is to give Purim two dates since it was originally practiced across two days. So Joseph takes the first date and Benjamin the second.
Gad is the table of bread in the tent, so his alignment with the opening of Unleavened Bread is a wonderful match. His brother, Asher, matches the closing assembly of this holiday.
Naphtali has "goodly words." Words are not something, they are a description or communication of something. Words are like First Fruits, a sample of the thing, but not the thing. They give you an essence. This is why Jesus says things like words reveal the heart.
Manasseh makes sense on New Grain since it counts 50 days from the First Fruits holiday. 50 is a common prophetic number for Manasseh and matches his 50 states.
Simeon lands on Trumpets, which matches his theme of giving/receiving counsel.
Levi makes lots of sense on the day of Atonements since only the high priest entered the holy of holies in the temple with blood once a year on the day of Atonement and the priests were always from the tribe of Levi.
Purim makes sense for Benjamin, since modern Israel is basically a Jewish state and Purim is a Jewish holiday instated after ancient Israel was scattered into the world.
