Does anyone remember seeing anywhere mentioned, that the words "Ve'chara Af" should preferably be written on one line in Tefillin? I remember a long time ago seeing something mentioned in a Sefer to that effect, but cannot remember where. We're not talking strictly Halachakly speaking, but some sort of Inyan besides. If anyone encountered something like that in any Sefer, I would greatly appreciate if they would enlighten me. Thank You.
