In plain words
...having tasted it himself, he passes what remains to the other wife. He washes his hands, fills the water-vessel, and sprinkles her three times, saying: 'Rise up and go, Viśvāvasu — seek another, a girl not yet given away. Let this wife be joined with her husband.'

...(having tasted it) he gives [the remainder] to the other [wife]. Having washed his hands, having filled the water-vessel, with that he sprinkles her thrice, [saying]: 'Rise up from here, Viśvāvasu; seek another, one still with her own people; [let this] wife [be united] together with her husband,' thus.
