John Chrysostom
Due to their frequent forgetfulness of God's blessings, the Lord instructed them to inscribe His wonders on special leaves and attach these to their hands, which is why it is said, "Let them be steadfast before thy eyes." These were known as phylacteries, similar to how many women today wear their scriptures around their necks. They took great care in creating wide straps for these leaves and in broadening the edges of their garments (Matthew 23:5), which highlighted their excessive vanity. Why do you take pride in this outward display? Is this the essence of your righteousness? What benefit will these practices bring if you disregard the lessons they signify? God desires not for you to merely adorn them, but to remember His mercies. If acts of charity and prayer, which necessitate our effort and are truly commendable, do not warrant your praise, why then, O Jew, do you elevate yourself through actions that reveal your neglect?
