Luke 19:42

If thou also hadst known. It is a broken sentence, as it were in a transport of grief; and we many understand, thou wouldst also weep. Didst thou know, even at this day, that peace and reconciliation which God still offers to thee. (Witham) --- What can be more tender than the apostrophe here made use of by our Saviour! Hadst thou but known, &c. that is, didst thou but know how severe a punishment is about to be inflicted upon thee, for the numberless transgressions of thy people, thou likewise wouldst weep; but, alas! hardness in iniquity, thou still rejoicest, ignorant of the punishment hanging over thy head. Just men have daily occasion to bewail, like our blessed Redeemer, the blindness of the wicked, unable to see, through their own perversity, the miserable state of their souls, and the imminent danger they are every moment exposed to, of losing themselves for ever. Of these, Solomon cries out; (Proverbs ii. 13.) They leave the right way, and walk through dark ways. We ought to imitate this compassion of our blessed Redeemer; and, as he wept over the calamities of the unfortunate Jerusalem, though determined on his destruction; so we ought to bewail the sins not only of our friends, but likewise of our enemies, and daily offer up our prayers for their conversion. (Dionysius)
