According to Srila Visvanatha Cakravarti, in this verse Vasudeva offers himself and his wife as excellent examples of those who are materially deluded. Although at the time of His birth in Kamsa's prison Lord Krishna told Vasudeva and Devaki that His mission was to rid the earth of unwanted kshatriyas, still His two parents could not avoid thinking of Him as their helpless son who needed protection from King Kamsa. In reality, of course, both Vasudeva and Devaki were participating in the divine pastime of the Lord's birth under the perfect direction of His internal energy; only out of transcendental humility does Vasudeva criticize himself in this way.
