Deuteronomy 30:14

Heart. Septuagint add, "and in thy hands." Thou art often obliged to talk about the law, and to learn it by heart. Nothing hinders thee, with the grace of God, from putting it in practice. (Calmet) --- No teacher could more plainly inculcate the liberty of the human will. (Theodoret, q. 38.; St. Augustine, de Nat. 69.; St. Ambrose; &c.) (Worthington)
