5. Phylacteries and Borders.—Through a traditional interpretation of Exo. 13:9 and Deut. 6:8, the Hebrews adopted the custom of wearing phylacteries, which consisted essentially of strips of parchment on which were inscribed in whole or in part the following texts: Exo. 13:2-10 and 11-17; Deut. 6:4-9, and 11:13-21. Phylacteries were worn on the head and arm. The parchment strips for the head were four, on each of which one of the texts cited above was written. These were placed in a cubical box of leather measuring from 1/2 inch to 1-1/2 inches along the edge; the box was divided into four compartments and one of the little parchment rolls was placed in each. Thongs held the box in place on the forehead between the eyes of the wearer. The arm phylactery comprized but a single roll of parchment on which the four prescribed texts were written; this was placed in a little box which was bound by thongs to the inside of the left arm so as to be brought close to the heart when the hands were placed together in the attitude of devotion. The Pharisees wore the arm phylactery above the elbow, while their rivals, the Sadducees, fastened it to the palm of the hand (see Exo. 13:9). The common people wore phylacteries only at prayer time; but the Pharisees were said to display them throughout the day. Our Lord's reference to the Pharisees' custom of making broad their phylacteries had reference to the enlarging of the containing box, particularly the frontlet. The size of the parchment strips was fixed by rigid rule.
