Srimad-Bhagavatam: Canto 4 - Chapter 1 - Verse 16


द‍ृढव्रत: सत्यसन्धो ब्रह्मण्यो वृद्धसेवक: । शरण्य: सर्वभूतानां मानदो दीनवत्सल: ॥ १६ ॥


dṛḍha-vrataḥ satya-sandhobrahmaṇyo vṛddha-sevakaḥśaraṇyaḥ sarva-bhūtānāṁmānado dīna-vatsalaḥ


The King will be firmly determined and always situated in truth. He will be a lover of the brahminical culture and will render all service to old men and give shelter to all surrendered souls. Giving respect to all, he will always be merciful to the poor and innocent.


The word vṛddha-sevakaḥ is very significant. Vṛddha means “old men.” There are two kinds of old men: one is old by age, and another is old by knowledge. This Sanskrit word indicates that one can be older by the advancement of knowledge. King Pṛthu was very respectful to the brāhmaṇas, and he protected them. He also protected persons advanced in age. Whatever the King would decide to do, no one would be able to stop. That is called dṛḍha-saṅkalpa, or dṛḍha-vrata.
