1.34 The list of kin again Arjuna speaks

आचार्याः पितरः पुत्रास्तथैव च पितामहाः
मातुलाः श्चशुराः पौत्राः श्यालाः सम्बन्धिनस्तथा

āchāryāḥ pitaraḥ putrās tathaiva cha pitāmahāḥ
mātulāḥ śhvaśhurāḥ pautrāḥ śhyālāḥ sambandhinas tathā

teachers, fathers, sons, grandfathers, uncles, fathers-in-law, grandsons, brothers-in-law — all of them kin.

Explanation

The list of kin, again.

Teachers, fathers, sons, grandfathers, uncles, fathers-in-law, grandsons, brothers-in-law — all of them kin.

He has already listed them in 1.26. Repeating it is what grief does, and the text lets him do it. The Gita's picture of a person in this state includes saying the same thing twice.
