Set a watch, O Lord, upon our tongue:
That we many never speak the cruel word which is untrue;
or, being true, is not the whole truth;
or, being wholly true, is merciless;
for the love of Jesus Christ our Lord.
Amen.
from Daily Prayer by Eric Milner-White and G.W. Briggs (London: Oxford University Press) quoted in Prayers for Students edited by John W. Doberstein, Chaplain of Muhlenberg College, Student Service Commission, National Lutheran Council, 1947.
Bene orasse est bene studuisse.
