Nyrop writes that the most common example is the "intense feeling which knits parents to their offspring", but he adds that kisses of affection are not only common between parents and children, but also between other members of the same family, which can include those outside the immediate family circle, "everywhere where deep affection unites people." The tradition is written of in the Bible, as when Esau met Jacob after a long separation, he ran towards him, fell on his neck, and kissed him (), Moses greeted his father-in-law and kissed him (), and Orpah kissed her mother-in-law before leaving her (). The family kiss was traditional with the Romans and kisses of affection are often mentioned by the early Greeks, as when Odysseus, on reaching his home, meets his faithful shepherds.
