Daily Aliya for Naso, Revi’i (4th Aliya)
From Chabad.org: This rather lengthy Aliya contains three concepts: 1) The ceremony for the sotah, a suspected adulteress who was witnessed going into seclusion with another man–despite being warned not to associate with that individual. The woman is brought to the Temple. This section of the Torah is written on parchment and then soaked in water until the ink dissolves. The woman drinks the water. If she indeed willingly committed adultery, her belly miraculously swells and she dies a gruesome death. If she is unharmed by the waters, she is cleared of any suspicion. 2) The laws of the individual who vows to be a Nazirite. Such a person must abstain from wine and grape products, allow his/her hair to grow, and may not come in contact with a human corpse. At the conclusion of the term of the vow, the Nazirite brings certain offerings in the Temple. 3) The priestly blessings.
