Chabad.org — English translation + Rashi
Torah Temimah citing Sanhedrin / Koheles (pointer only — not TT’s gloss). “אסופות” in Koheles is read as Sanhedrin — “gather for Me seventy men.”
English: “Asufos” means only a Sanhedrin, as you say “Gather for Me seventy men of the elders of Israel.”
Scriptural name for the court — the gathering of elders is the model for every Sanhedrin.
Wisdom is stronger when it emerges from an assembly, not from a single voice.
