Chizkiah ben Manoach (Chizkuni)

Chizkiah ben Manoach lived in the 13th century, probably in France. The details of his biography are unknown. He is the author of "Chizkuni," a popular commentary on the Torah, which is actually a compilation of insights culled from Midrash, alongside the writings of 20 rishonim, including Rashi, Rashbam and Ibn Ezra. However, with the notable exception of Rashi, Chizkuni does not name any of his sources, as he felt that one should focus on the message rather than the messenger.
