Why is Michael against abortion?

 

(Numbers 11:11-12)

11 Moses said to the Lord, "Why have you brought this trouble on your servant? What have I done to displease you that you put the burden of all these people on me?
12 Did I conceive all these people? Did I give them birth? Why do you tell me to carry them in my arms, as a nurse carries an infant, to the land you promised on oath to their ancestors?"
