Luke 14:31

The order of the words requires careful examination of the cues—the datives, the participles, prepositions, and the genitives to sort out the right order.

Two kings unite, effectively doubling ten thousand to twenty thousand, to fight against the one coming against him. In particular, the words μετὰ "in company with" and ἐπ’ "against" are significant prepositions in the context of war. μετὰ "with" lacks any real force in terms of "fighting with" as one might say in modern idiom, where "with" is taken as the same as "against." But regardless, the sense is all but demolished by the explicit use of ἐπ’ "against/upon" in the very same verse.
