The first three articles are for Tisha B'Av, the major 25 hour fast from Monday sunset to Tuesday nightfall,
in recollection of the destruction of the two Holy Temples in Jerusalem.
The last three are for the Weekly Reading, Vaet'chanan, known as the "Shabbat of Consolation" ("Nachamu") and which contains the "Shema Yisrael" prayer and the Ten Commandments.
