Be happy with those who are happy, and cry with those who are crying.
Rejoice with them that do rejoice, and weep with them that weep.
Rejoice with those who rejoice [sharing others' joy], and weep with those who weep [sharing others' grief].
Rejoice with them that rejoice; weep with them that weep.
Rejoice with those who are rejoicing. Weep with those who are weeping.
