We are now deep in the Three Weeks between fast days (see articles #1-2), leading up to Tisha b'Av, commemorating the destruction of the Holy Temples in Jerusalem.
For the last three months, Israel and the Diaspora have been out of sync, with different weekly readings, due to the differing lengths of the respective Passover celebrations. Now, this week we are all reading Masei, whether singly or combined with Matot. Therefore, we will celebrate this unifying Weekly Reading with 3 articles (5-7).
while #4 is for the second chapter in the third cycle of Pirkei Avot, for those who continue to study it on Shabbat afternoons throughout the summer.
Friday is Rosh Chodesh Av, when the restrictions of this three-week mourning period for the Holy Temples in Jerusalem intensify for the final 9-10 days. Read all about it next week.

(Those of you in ISRAEL should click to MASEI for articles on the Weekly Reading there.)
