Is it a mitzvah to have babies? The Jewish Lifecycle

(21) He used to say: At five years of age the study of Scripture; At ten the study of Mishnah; At thirteen subject to the commandments; At fifteen the study of Talmud; At eighteen the bridal canopy; At twenty for pursuit [of livelihood]; At thirty the peak of strength; At forty wisdom; At fifty able to give counsel; At sixty old age; At seventy fullness of years; At eighty the age of “strength”; At ninety a bent body; At one hundred, as good as dead and gone completely out of the world.

(24) God said, “Let the earth bring forth every kind of living creature: cattle, creeping things, and wild beasts of every kind.” And it was so.(25) God made wild beasts of every kind and cattle of every kind, and all kinds of creeping things of the earth. And God saw that this was good.(26) And God said, “Let us make humankind in our image, after our likeness. They shall rule the fish of the sea, the birds of the sky, the cattle, the whole earth, and all the creeping things that creep on earth.”
(27) And God created humankind in the divine image,
creating it in the image of God—
creating them male and female.(28) God blessed them and God said to them, “Be fertile and increase, fill the earth and master it; and rule the fish of the sea, the birds of the sky, and all the living things that creep on earth.”(29) God said, “See, I give you every seed-bearing plant that is upon all the earth, and every tree that has seed-bearing fruit; they shall be yours for food.(30) And to all the animals on land, to all the birds of the sky, and to everything that creeps on earth, in which there is the breath of life, [I give] all the green plants for food.” And it was so.(31) And God saw all that had been made, and found it very good. And there was evening and there was morning, the sixth day.

(6)A man may not neglect the mitzva to be fruitful and multiply unless he already has children. Beit Shammai say: One fulfills this mitzva with two males, and Beit Hillel say: A male and a female, as it is stated: “Male and female He created them” (Genesis 5:2). If a man married a woman and stayed with her for ten years and she did not give birth, he is no longer permitted to neglect the mitzva to be fruitful and multiply. Consequently, he must either divorce her and marry someone else, or take another wife while still married to her. If he divorced her she is permitted to marry another man, as it is not necessarily on her account that she and her first husband did not have children, and the second husband is permitted to stay with her for ten years. And if she had a miscarriage, he counts the ten years from the time of the miscarriage.A man is commanded with regard to the mitzva to be fruitful and multiply, but not a woman. Rabbi Yoḥanan ben Beroka says that a woman is also commanded, as the verse states with regard to both of them: “And God blessed them, and God said to them: Be fruitful and multiply” (Genesis 1:28).

Rabbi Asi said: The Messiah, son of David, will not come until all the souls of the body have been finished, i.e., until all souls that are destined to inhabit physical bodies will do so. As it is stated: “For the spirit that enwraps itself is from Me, and the souls that I have made” (Isaiah 57:16). It is taught in a baraita that Rabbi Eliezer says: Anyone who does not engage in the mitzva to be fruitful and multiply is considered as though he sheds blood, as it is stated: “Whoever sheds the blood of man, by man shall his blood be shed” (Genesis 9:6), and it is written immediately afterward: “And you, be fruitful and multiply” (Genesis 9:7).Rabbi Ya’akov says: It is as though he diminishes the Divine Image, as it is stated: “For in the image of God He made man” (Genesis 9:6), and it is written immediately afterward: “And you, be fruitful and multiply” (Genesis 9:7). Ben Azzai says: It is as though he sheds blood and also diminishes the Divine Image, as it is stated: “And you, be fruitful and multiply,” after the verse that alludes to both shedding blood and the Divine Image.They said to ben Azzai: There is a type of scholar who expounds well and fulfills his own teachings well, and another who fulfills well and does not expound well. But you, who have never married, expound well on the importance of procreation, and yet you do not fulfill well your own teachings. Ben Azzai said to them: What shall I do, as my soul yearns for Torah, and I do not wish to deal with anything else. It is possible for the world to be maintained by others, who are engaged in the mitzva to be fruitful and multiply.

MISHNA:A man is commanded with regard to the mitzva to be fruitful and multiply, but not a woman. Rabbi Yoḥanan ben Beroka says that a woman is also commanded, as the verse states with regard to both of them: “And God blessed them, and God said to them: Be fruitful and multiply” (Genesis 1:28).GEMARA:From where are these matters derived, that a woman is not obligated in the mitzva to be fruitful and multiply? Rabbi Ile’a said in the name of Rabbi Elazar, son of Rabbi Shimon: The verse states: “Be fruitful and multiply, and fill the land and conquer it” (Genesis 1:28). It is the manner of a man to conquer and it is not the manner of a woman to conquer. Consequently, it is evident that the entire command, including the mitzva to be fruitful and multiply, was given only to men and not to women.The Gemara raises a difficulty. On the contrary, the plural term: “And conquer it [vekhivshuha],” indicates that the two of them are included. Rav Naḥman bar Yitzḥak said: It is written in the Torah without the letter vav, so that it can be read: And conquer it [vekhivsha], in the singular. Rav Yosef said: The proof is from here: “And God said to him: I am God Almighty, be fruitful and multiply [perei urvei]” (Genesis 35:11), which is in singular, and it does not state: Be fruitful and multiply [peru urvu] in the plural.The Gemara cites other statements made by Rabbi Ile’a in the name of Rabbi Elazar, son of Rabbi Shimon. And Rabbi Ile’a said in the name of Rabbi Elazar, son of Rabbi Shimon: Just as it is a mitzva for a person to say that which will be heeded, so is it a mitzva for a person not to say that which will not be heeded. One should not rebuke those who will be unreceptive to his message.

The Gemara asks: What conclusion was reached about this issue? The Gemara suggests: Come and hear, as Rabbi Aḥa bar Ḥanina said that Rabbi Abbahu said that Rabbi Asi said: There was an incident that came before Rabbi Yoḥanan in the synagogue of Caesarea involving a woman who wanted a divorce from her husband after ten years of childless marriage, and he said that the husband must divorce her and give her the payment for her marriage contract. If it enters your mind to say that she is not commanded to be fruitful and multiply, what is payment for a marriage contract doing here? Why does she have a right to demand to be divorced and to receive the payment for her marriage contract?The Gemara responds: Perhaps that was in a case when she came to demand a divorce due to another claim, i.e., she wanted children for a reason other than the fulfillment of the mitzva to be fruitful and multiply. Since this claim has merit, her husband must divorce her and pay her marriage contract.This is like the case of a certain woman who came before Rabbi Ami and requested a divorce due to her husband’s inability to father children. She said to him: Give me the payment for my marriage contract. He said to her: Go away, as you are not commanded to be fruitful and multiply and have no right to demand a divorce. She said to him: In her old age, what will be with this woman, i.e., if I have no children, who will take care of me when I grow old? Rabbi Ami said: In a situation such as this, we certainly force the husband to divorce her and pay her marriage contract.The Gemara relates a similar incident: A certain woman came before Rav Naḥman and requested a divorce due to her husband’s inability to father children. He said to her: You are not commanded to be fruitful and multiply. She said to him: Does this woman not require a staff for her hand and a hoe for her burial? In other words, the woman said that she wanted children so that they could care for her in her old age and bury her when she would die. Rav Naḥman said: In a case such as this, we certainly force the husband to divorce her.

(4) And (Adam) was at his leisure in the garden of Eden, like one of the ministering angels. The Holy One, blessed be He, said: I am alone in My world and this one (Adam) also is alone in his world. There is no propagation before Me and this one (Adam) has no propagation in his life; hereafter all the creatures will say: Since there was no propagation in his life, it is he who has created us. It is not good for man to be alone, as it is said, "And the Lord God said, It is not good for man to be alone; I will make him an help meet for him …" (Gen. 2:18).

(5) Rabbi Jehudah said: If he be worthy she shall be an help meet for him; if not, she shall be against him to fight him.
