Reference for Chagigah 16:14

ואלא דלית ליה אוכלין האי דלא אקרבינהו דלית ליה אוכלין

If you'll say [the reason he didn't bring half of them is because] there were no more dependents [to eat his food], that means that they weren't brought because he didn't have dependants [and he did separate them for the first day].
