Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 33

Sanskrit:

हेलनं गिरिशभ्रातुर्धनदस्य त्वया कृतम् ।यज्जघ्निवान् पुण्यजनान् भ्रातृघ्नानित्यमर्षित: ॥ ३३ ॥

ITRANS:

helanaṁ giriśa-bhrāturdhanadasya tvayā kṛtamyaj jaghnivān puṇya-janānbhrātṛ-ghnān ity amarṣitaḥ

Translation:

My dear Dhruva, you thought that the Yakṣas killed your brother, and therefore you have killed great numbers of them. But by this action you have agitated the mind of Lord Śiva’s brother Kuvera, who is the treasurer of the demigods. Please note that your actions have been very disrespectful to Kuvera and Lord Śiva.

Purport:

Lord Manu stated that Dhruva Mahārāja had been offensive to Lord Śiva and his brother Kuvera because the Yakṣas belonged to Kuvera’s family. They were not ordinary persons. As such, they have been described as puṇya-janān, pious men. Somehow or other the mind of Kuvera had been agitated, and Dhruva Mahārāja was advised to pacify him.
