Then Hashem commands Moshe to tell Bnei Yisrael that on the 10th of the month they will take in a lamb or kid to be slaughtered on the 14th. Hold this thought. Since each tribe parallels one of the 12 months, this parallel can also be said for the first 12 days of Nisson. This year, the first of the month falls out on Shabbos. This first day parallels, of course, the first month which is Nisson itself.
Every month also has a 'tsiruf'.
The 4 letter Name of Hashem as 24 possible letter combinations. Since two of the letters are the same, the 24 ends up being a duplicate set of 12. Each of these twelve different combinations is called a 'tsiruf' and is found in four words somewhere in the Tanach. May all are prayers enter the inner chambers of Hashem. May the desecraters of Shabbos do tshuva.
