In synagogues using the Triennial system, 5783 is year 1 and the Torah reading is Numbers 25:10-26:51.This is a very busy Torah portion: it begins with a commendation of Pinchas for his actions at the end of last week's portion. An order to defeat Midianites. A census listing descendants of each tribe. Apportionment of the Land. Inheritance for Zelophehad's daughters. Joshua as Moses's successor. Offerings for all occasions. This lengthy list of offerings is broken up with appropriate pieces read as the maftir portion on each of the holidays. It is one of the first pages checked when examining a Torah because it is the most used page!
