Phylacteries (tephillin). These are strips of leather to which is attached little square box made of parchment and painted black. The box contains four parts of the Torah written on parchment: Exodus 13:1 and 11:6; Deuteronomy 6:4-9; 11:13-21. According to Deut 6:4-9 two phylacteries were used, one for the head and one for the arm. These (called frontlets in Deuteronomy) were put on in such a way that one box rested on the head, between the eyes (seat of the mind) and the other on the left arm opposite the heart (seat of the actions and the emotions, denoting that one loves the Lord with one's heart). They are referred to as phylacteries in the New Testament (Mat 23:5).
