[3] Hillel Bakis' books deal with topics related to Judaism and Jewish traditions (exegesis and liturgy, grammar, folklore, oral literature, etc.).
With his book on the longest of 'the Psalms (To read the Psalms, 2014) "the author surprises with the comment about his commentary: he approaches the grammatical side, does not hesitate to report the other commentators and to criticize them, explains the moral significance of the verses studied, and ends up giving the reader a complete idea of the texture of the verses "(Rav H. Kahn 2015b); "Hillel Bakis translated each verse ... giving a precise reading of each word, taking into account its grammatical structure, while explaining it" (G. Touaty, 2015).
Hillel Bakis extended his commentary on the Pentateuch with a series of books on the Prophets, designed to enlighten the understanding of the texts read on the synagogue services on feasts, fasts, and chabbats (2017, 2018a, 2018b, 2019, 2020).
Hillel Bakis presents (2021d) a detailed inventory of units of measure (length, surface, volume, weight, monetary values, time, temperature) and currencies of the Bible and the Talmud.
[13] His study on the new-year trees (Tu bishvat), he gives details on the different customs and the complete ‘seder’ of the celebration.
In 1992, Hillel Bakis published manuscript fragments of a 16th-century Moroccan rabbinical work (that of Rabbi Isaiah Bakish).
