Week 39 is the week of Rosh Chodesh Tammuz and Gimmel Tammuz. The Torah portion section for this week describes how the mannah did not fall on the Sabbath. This made the people nervous, as Rashi explains:
Daf Lamed Tet (Folio 39) of Sotah relates the laws of proper behavior in a synagogue, during the reading of the Torah and the blessing of the Kohanim. The daf also mentions the verses said by the congregation during the priestly blessing, which focus on Zion; during a blessing said on the afternoon of a fast day, the verses are about pleading to Hashem to save us from our exile. The synagogue is known as a mikdash me’at, a miniature Temple. It is during this time of the year, that we focus on Zion, on the Temple’s destruction, and its ultimate rebuilding.
