Berakhot 23

If one needs to go to the bathroom during shmone esreh, what does one do? Can one pray when one needs to go to the bathroom? Can one bring tefillin into the bathroom? Can one bring them in by carrying them in one's hand or wrapped in something? There are dangers if one leaves them outside and therefore Beit Hillel permits bringing them into a permanent bathroom in one's hand. Would he allow it also in a temporary bathroom? It was also believed that there were spirits in the bathroom and some brought tefillin there to protect them from the spirits. Why would there be a difference? Before sitting down to a meal, one should try to use the bathroom. Also one should not wear one's tefillin when eating, in case one gets drunk? Can one put money in a head covering that is being used to wrap one's tefillin? Can one sleep with tefillin under one's pillow? Is it allowed even if his wife is in bed with him?
