Gradual (Ps. 16: 8 & 2)
Custódi me, Dómine, ut pupíllam óculi: sub umbra alárum tuárum prótege me. Vs. De vultu tuo judícium meum pródeat: óculi tui vídeant æquitátem.

Keep me, O Lord, as the apple of Thine eye: protect me under the shadow of Thy wings. Vs. Let my judgment come forth from Thy countenance: let Thine eyes behold the thing that is equitable.
