From time immemorial, great care has been taken concerning the precise transmission of the text of the Tanakh, which has been regarded as having the utmost importance.

Chazal were altogether proficient with the entirety of the biblical text, as we may deduce from the corpus of midrashim, in which verses from throughout the Tanakh are treated. In addition, the Sages also concerned themselves with the clarification of the precise text of the Tanakh, and many sources testify to the tremendous care taken concerning textual details.

It is clear that, in general, Chazal worked with a single textual version that they all shared. Nevertheless, this does not mean that there was a single textual version that was agreed upon absolutely in all its details, as can be gathered from various sources in Chazal.
