wrong on both counts
Phylactery, Hebrew
Tefillin, also spelled
Tephillin, or
Tfillin, in Jewish religious practice, one of two small, black leather, cube-shaped cases containing
Torah texts written on parchment, which, in accordance with
Deuteronomy 6:8 (and similar statements in Deuteronomy 11:18 and Exodus 13:9, 16), are to be worn by male Jews of 13 years and older as reminders of God and of the obligation to keep the Law during daily life. The name phylactery is derived from the Greek
phylakterion, meaning
amulet.
According to rabbinic regulations, one of the phylacteries is worn on the left arm facing the heart and
the other on the forehead at the morning service (except on the Sabbath and festivals) and at the afternoon service on the Ninth of Av.
The
tefillin are worn in a prescribed manner so as to represent the letters
shin, daleth, and
yod, which taken together form the divine name
Shaddai. The hand phylactery (
tefillin shel yad) has one compartment with the texts written on a single parchment; the head phylactery (
tefillin shel rosh) has four compartments, each with one text. The extracts are Exodus 13:1–10, 11–16; Deuteronomy 6:4–9, 11:13–21. Reform Jews interpret the biblical commandment in a figurative sense and, hence, do not wear phylacteries. Because of rabbinic indecision about the exact sequence of the four scriptural passages, very pious Jews may have two pairs of phylacteries.

now how did I know that and how do you consistently get things wrong?
