Bhagavad Gita Chapter 1.26
tatrāpaśyat sthitān pārthaḥ
pitṝn atha pitāmahān
ācāryān mātulān bhrātṝn
putrān pautrān sakhīḿs tathā
śvaśurān suhṛdaś caiva
senayor ubhayor api
Translation
There Arjuna could see, within the midst of the armies of both parties, his fathers, grandfathers, teachers, maternal uncles, brothers, sons, grandsons, friends, and also his fathers-in-law and well-wishers.
