Judges 3:2

might know The verb, instead of governing a direct object, is followed by a fresh clause to teach them war; the LXX relieves the awkwardness by omitting might know, -only for the sake of the generations … to teach them war." The incompleteness of the conquest was not a punishment for Israel's unfaithfulness to the covenant (Judges 2:20-21), nor a test of Israel's steadfastness (Judges 2:23; Judges 3:4-6), but a discipline 1 [24] designed to train Israel to hold its own and ascribe its victories to Jehovah's help.

[24] Cf. Livy 39:1. Is hostis (the Ligures) velut natus ad continendam inter magnorum intervalla bellorum Romanis militarem disciplinam erat.

at the least such only such; the repetition is clumsy; the rest of the verse looks like an explanatory gloss.
