Bhagavad Gita 4.15

एवं ज्ञात्वा कृतं कर्म पूर्वैरपि मुमुक्षुभिः।कुरु कर्मैव तस्मात्त्वं पूर्वैः पूर्वतरं कृतम्॥

evaṃ jñātvā kṛtaṃ karma pūrvairapi mumukṣubhiḥ |kuru karmaiva tasmāttvaṃ pūrvaiḥ pūrvataraṃ kṛtam ||

Having known this, the ancient seekers of freedom also performed action; therefore, do thou also perform action, as the ancients did in days of yore.

In the light of wisdom, our ancestors who sought deliverance performed their acts. Act thou also as our fathers of old did.

Our plain-language meaning of this verse is waiting for scholar review.
