Acts 20:37

They kissed him. These marks of tenderness are dictated by nature, and have always been used between friends, who were separating from each other, or who meet after a long absence. The Scripture furnishes us with numberless examples of it. (Calmet) --- He likewise prayed, as he usually did, when he bade his last farewell. See his last adieus with the Tyrians, (chap. xxi. 5. 6.) were they all kneeled down to pray on the shore. This is also reasonable, and becoming a Christian. It is a sign of communion and mutual charity, and implores a prosperous voyage for those who were departing, whilst those who remained, cherish in their mind the remembrance of the virtues of their absent friend. (Menochius) --- The mind of man cannot conceive a finer subject for the painter than this melting separation. After the discourse, we see St. Paul falling on his knees, and praying with them all for the last time; an general burst of tears takes place, when they are told that they are to see their father's face no more; they fall upon his neck and kiss him; and with hearts full of grief and gratitude, they accompany him on his way to the very ship which is to transport their father, friend, and benefactor, to other souls, who wanted the charitable assistance of the man of God.
