Thomas Aquinas

Third, as to touch, which is strongest in the fingers: rings: therefore we offer . . . rings (Num 31:50). Fourth, as to sight: jewels hanging on the forehead, with which the women of Egypt were adorned: you shall take onyx stones, and precious stones to adorn the ephod and the rational (Exod 25:7). He makes no mention of taste, because its instrument is interior and is not adorned.
