Final answer:
The idea that Yitzchak (Isaac) instituted Mincha, one of the daily prayers in Judaism, comes from an interpretation of Genesis 24:63 in the Torah. This interpretation and tradition are recognized within the field of Jewish Studies and Jewish Theology.
Step-by-step explanation:
The assertion that Yitzchak (Isaac) instituted Mincha, one of the daily prayers in Judaism, comes from a textual analysis of the Torah, specifically Genesis 24:63. In the verse, it is stated that Isaac went 'lasuach' in the field which is interpreted by many commentators to mean he was praying. This interpretation gave rise to the tradition that Isaac instituted Mincha, which is often associated with the afternoon and thus aligns with the timing described in the verse.
This claim, like many in religious studies, is reliant on interpretation and tradition. Therefore, it is seen as valid within the context of Jewish Studies and Jewish Theology, where the Torah and interpretations of it constitute a significant portion of the foundation of the spiritual belief system.
