I answer that, Three things may be considered in relation to knowledge and understanding: first, the reception thereof; secondly, the use; and thirdly, their preservation. Now the reception of knowledge or understanding, is by means of teaching and learning, and both are prescribed in the Law. For it is written (Deut. 6:6): "These words which I command thee . . . shall be in thy heart." This refers to learning, since it is the duty of a disciple to apply his mind to what is said, while the words that follow—"and thou shalt tell them to thy children"—refer to teaching.

The use of knowledge and understanding is the meditation on those things which one knows or understands. In reference to this, the text goes on: "thou shalt meditate upon them sitting in thy house," etc.

Their preservation is effected by the memory, and, as regards this, the text continues—"and thou shalt bind them as a sign on thy hand, and they shall be and shall move between thy eyes. And thou shalt write them in the entry, and on the doors of thy house." Thus the continual remembrance of God's commandments is signified, since it is impossible for us to forget those things which are continually attracting the notice of our senses, whether by touch, as those things we hold in our hands, or by sight, as those things which are ever before our eyes, or to which we are continually returning, for instance, to the house door. Moreover it is clearly stated (Deut. 4:9): "Forget not the words that thy eyes have seen and let them not go out of thy heart all the days of thy life."
