Watch therefore. This is the lesson which the Lord draws from the parable, as elsewhere he gives the same warning, e.g. Luke 12:35, repeated by the apostle (1 Thessalonians 5:2, 1 Thessalonians 5:6).
Ye know neither the day nor the hour [wherein the Son of man cometh]. The words in brackets are omitted by the earlier uncials, the Vulgate, Syriac, etc., and are to be regarded as an exegetical interpolation (comp.
Matthew 24:42). Tertullian well says, "Ut pendula expectatione solicitude fidei probetur, semper diem observans, dum semper ignorat, quotidie timens quod quotidie sperat" ('De Anima,' 33). It remains to observe that, mystically, Christ is the Bridegroom, who celebrates his nuptials with his bride the Church, and comes to conduct her to heaven; those who are ready will accompany him and enter into the joy of their Lord; those who have not made their calling sure will be shut out.
