Final answer:
According to the teachings of Jesus, Christians are not instructed to multiply harm like Lamech, but rather to love and forgive their enemies.
Step-by-step explanation:
According to the teachings of Jesus, Christians are not instructed to multiply in the same sense as Lamech multiplied his vengeance on those who might harm him. The teachings of Jesus emphasize love, forgiveness, and reconciliation, rather than revenge and multiplication of harm. For example, Jesus taught his followers to love their enemies and to turn the other cheek when faced with harm or injustice.
