The Torah portion is Terumah, Exodus 25:1-27:19. In synagogues using the Triennial system, 5785 is year 3 and the Torah reading is Exodus 26:31-27:19.
Terumah means Offering and this parshah speaks of the extensive offerings collected for the building of the temporary Sanctuary in the wilderness. It provides detailed specs for the Sanctuary and various accoutrements, including the Aron (the Ark, aka Indiana Jones's Lost Ark), the Shulchan (Table), the Menorah (Candelabrum), the Mishkan (Tabernacle), the Ohel (Tent), and the Mizbei'ach (Altar).There is a special seventh aliyah (7th piece of the Torah reading) for Rosh Chodesh Shabbat: Numbers 28:9-15. This portion lays out the offerings made on Rosh Chodesh (the beginning of the new month) when it occurs on a Shabbat.
There is a special maftir portion (the final piece of the Torah reading) for Shabbat Sheqalim: Exodus 30:11-16. This passage tells about the collection of a half-sheqel tax used to count a census and maintain the Tent of Meeting.
The haftarah is for Shabbat Sheqalim, II Kings 12:1-17. This passage speaks of using money from the people (like the money from the census) to repair the Temple.
In synagogues using the Sephardic tradition, the Haftarah is II Kings 11:17-12:17.
