28:1. A person is obliged to touch his Tefillin (1) regularly (2) so as not to forget about them, and he should touch (3) the shel yad (4) first. When one says 'And you shall bind them for a sign on your arm' he should touch the shel yad, and when he says 'And they shall be as frontlets between your eyes' he should touch the shel rosh.
28:2. One (5) takes off the tefillin of the head first because it is written 'and _they_ should be for totafos between your eyes,' which implies that as long as they are between your eyes (ie. so long as you are wearing the tefilla "shel rosh") there should be two. One must remove the tefillin of the head while (6) standing. He should be put the tefilla of the head in the tefillin bag (7) and then put the tefilla of the hand ("shel yad") on top of it, in order that he will automatically touch the "shel yad" (8) first when he comes to put them on in the morning.
