[2] Voet's most famous work is his Commentarius ad Pandectas (i.e. Commentary on the Digest) (1698).

Unlike other jurists of his day, Voet's Commentary on the Digest was not a mere academic treatise but also an attempt to show how that law applied day-to-day in practice.

While the Commentary shows signs of legal humanism, it may also be considered a Dutch form of Usus modernus Pandectarum.

Unlike the work of Hugo Grotius and Simon van Leeuwen with which Voet's Commentary has been compared, Voet, as a teacher of law, wrote in Latin and not Dutch, as Latin at the time was the teaching language.

Sir Henry de Villiers, Chief Justice of the Cape Colony and later of South Africa, made much use of Voet's Commentary.
