SB 6.5.9
katham sva-pitur adesam
avidvamso vipascitah
anurupam avijñaya
aho sargam karisyatha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Alas, your father is omniscient, but you do not know his actual order. Without knowing the actual purpose of your father, how will you create progeny?
