The Versicle Dominus vobiscum (The Lord be with you) may be said only by Bishops, Priests and Deacons.

Subscribers who have not been ordained at least to the diaconate must instead say Domine, exaudi orationem meam, with the Response Et clamor meus ad te veniat (O Lord, hear my prayer.  And let my cry come unto thee).

If this latter Versicle and Response has already been said immediately prior to the Dominus vobiscum (eg. during the Preces), it is not said a second time.
