Frontlets are small leather boxes called phylacteries that contain Hebrew texts from the Torah. They are traditionally worn by observant Jewish men on the forehead and arm during weekday morning prayers. The practice originates from biblical commands to bind God's commandments "as a sign on your hand, and as frontlets between your eyes," symbolizing the constant remembrance and obedience to God's law. The texts inside usually include passages such as the Shema (Deuteronomy 6:4-9) which emphasize love and devotion to God. The term "frontlet" is specifically tied to these forehead-worn amulets and appears in key Old Testament passages such as Exodus 13:16 and Deuteronomy 6:8 and 11:18. Historically, the frontlet is part of a religious tradition that physically manifests mindfulness of God's presence in daily life. The New Testament critiques the ostentatious use of frontlets by some Pharisees for showy piety (Matthew 23:5).
Additionally, the word "frontlet" can also mean an ornament or band worn on the forehead in a more general, non-religious sense.
