In this week's Torah Reading Bo, we find the first mention of Mezuzah on doorposts — the subject of the first two articles.

This is the first full week of the Jewish month of Shevat.
A mystical insight into the month based on the teachings of the Lubavitcher Rebbe is the subject of article #3.

This Shabbat - 4 Shevat, is the yahrzeit of Rabbi Yisrael Abuhatzira, or the “Baba Sali,” as he was affectionately known throughout the Jewish world.
Tens of thousands of people are expected to converge at his resting place in Netivot this week. Article #4 is a teaching from his equally famous grandfather.
