eligite hodie quod placet cui

Hi,

Below is a verse from Vulgata:

"sin autem malum vobis videtur ut Domino serviatis optio vobis datur eligite hodie quod placet cui potissimum servire debeatis utrum diis quibus servierunt patres vestri in Mesopotamia an diis Amorreorum in quorum terra habitatis ego autem et domus mea serviemus Domino."

I'm puzzled with the bold part, I try to interpret the meaning here as "(you)choose today what pleases you the most." But "cui" really gets me. What kind of role does...

eligite hodie quod placet cui
