The following verses are covered in this talk:

So, they moved ahead until when they met a boy, he killed him (the boy). He (Mūsā) said, “Did you kill an innocent soul while he did not kill anyone? You have committed a heinous act indeed.” [18:74]

As for the boy, his parents were believers. We apprehended that he would impose rebellion and infidelity upon them. We, therefore, wished that their Lord would replace him with someone better than him in piety, and more akin to affection. [18:80-81]
