That Jobab, King of the Idumaeans — of whom [in] Genesis 36 and 1 Paralipomenon [Chronicles] 1 — is that great exemplar of a most patient spirit, Job, I have taught (on Tobias, ch. 2, questions 5 and 6); and in that same opinion I see [to be] the good commentator on his book, our Pineda, and other more ancient [writers], whom R. Abraham Zacuth mentions (fol. 96, in the Iuchasin [Sefer Yuḥasin]). On that account I would believe [that] he who succeeded him — Husham the Temanite — held at this time the kingdom of the Idumaeans, or Amalekites. For that a little before Israel escaped from Egypt Job himself had died, the Seder Rabba (ch. 3) hands down. But this war was waged in the first year of this liberation, and indeed in the second month, or before the third month, as is had from the same book of Exodus (ch. 19, v. 1).
(col. 63, foot) — That year fell in the year of the founding of the world — by the reckoning of the same Seder, 2448; by Scaliger (book 5 On the Emendation of Time), 2454; by my own [reckoning], which is the middle [one], and is proved by me elsewhere, 2450.
