In Talmudical hermeneutics, asmachta is an allusion found in the Hebrew Bible for rabbinical prohibitions or any other Halakha.
Sometimes it isn't clear whether the verse has been quoted as an asmachta or as a source, which can lead to controversy over the de'oraita or derabanan quality of the law.
The Talmud says "Anyone who recites an unnecessary blessing violates the biblical prohibition: Thou shalt not take the name of the Lord thy God in vain".
The people, however, accepted these seven laws as tradition, connecting them with the verse as aid to memory.
"[8] Yom Tov of Seville objects to Maimonides' explanation, and claims that God himself devised the various asmachta sources and embedded them in the Torah as allusions to be used by the sages.
