res dedi mihi exposco

Hi,

below is a sentence from Livy:

Inde Iovem testem facit: "Si ego iniuste impieque illos homines illasque res dedi mihi exposco, tum patriae compotem me numquam siveris esse!"

My try for translation: Thence he makes Juppiter a witness. "If I beg that I've done something unjust and impious to the people and the state affairs (illasque res?),
then you will never allow me to have a say over the homeland."

I'm puzzled in regards with two points: 1) two verbs (dedi/exposco)...

res dedi mihi exposco
