550 Josephus reinforces the sub-theme of this segment, introduced in 162, 165 ( ζῆλος [“emulation”] here echoes ζηλωτής in 1.162). The language of “permeation” ( διαφοιτάω) will be repeated in 2.282-84. Since what Theophrastus records is the banning of the Korban oath, Josephus’ reasoning requires a triple inference: that the Korban oath is specifically “Judean,” that its ban indicates its popularity, and that this betokens the emulation of Judean customs in general. Only the first inference is supported in what follows. The second and third are hardly self-evident; cf. Josephus’ use of the Greek oath νὴ Δία(1.255).
