SB 10.1.52
evam vimrsya tam papam
yavad-atmani-darsanam
pujayam asa vai saurir
bahu-mana-purahsaram
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
After thus considering the matter as far as his knowledge would allow, Vasudeva submitted his proposal to the sinful Kamsa with great respect.
