The investigation of the Old Testament canon came to a close at the Synod of Jamnia.

True or False?

Answer: true

Explanation:

The Council of Jamnia, presumably held in Yavneh in the Holy Land, was a hypothetical late 1st-century council at which the canon of the Hebrew Bible was formerly believed to have been finalized and which may also have been the occasion when the Jewish authorities decided to exclude believers in Jesus as the Messiah from synagogue attendance, as referenced by interpretations of John 9:22 in the New Testament.[1] The writing of the Birkat ha-Minim benediction is attributed to Shmuel ha-Katan at the supposed Council of Jamnia.
