Kamsa did not expect to see Durga instead of the 8th male child. The whole episode left him stunned and he starts to speak life philosophy to Devaki & Vasudev.
This reading is a super condensed version from the original book, "Krishna" or "Krsna" by His Divine Grace A.C Bhaktivedanta Swami Srila Prabhupada, Founder - Acharya of ISKCON. This pastime is from Chapter 4, Kamsa Begins His Persecutions.
