דַּבֵּ֞ר אֶל־בְּנֵ֤י יִשְׂרָאֵל֙ לֵאמֹ֔ר אִשָּׁה֙ כִּ֣י תַזְרִ֔יעַ וְיָלְדָ֖ה זָכָ֑ר וְטָֽמְאָה֙ שִׁבְעַ֣ת יָמִ֔ים כִּימֵ֛י נִדַּ֥ת דְּוֺתָ֖הּ תִּטְמָֽא׃
Berbicaralah kepada bani Israel: Apabila seorang perempuan mengandung lalu melahirkan anak laki-laki, ia najis selama tujuh hari; ia najis sama seperti pada hari-hari haidnya, ketika tubuhnya sedang tidak sehat.

"When a woman conceives and gives birth to a male child..." In the Midrash (Vayikra Rabbah 14:2), "I will bring forth My righteousness; it is not far off, and My salvation shall not delay" (Isaiah 46:13). Rabbi Nathan said, "We calculate for the sake of our forefather Abraham. He who comes from afar." As it is written: "He renews His wonders" (Psalms 136:4), "Who makes new every day." Indeed, according to the simple understanding, what newness is there in a mother who gives birth every day? Then even renewal should become ordinary. But the matter is this: that the Holy One, blessed be He, makes something new out of the ordinary, and wonders will come into the hearts of those who await Him on everything to say, 'Who has created these?' As with our forefather Abraham, peace be upon him, for the world behaved as such for many years before Abraham came into the world, and there was no one to inquire and wonder about His conduct. And in the heart of Abraham, peace be upon him, there was a very great wonder (Genesis Rabbah 39:1). It can be said that the city without a leader: who is the owner of the city? And when the Holy One, blessed be He, saw that his question was not like the natural inquiries, but because he truly wanted to know who created these, in order to worship Him, and because of this, he despised all the pleasures of this world. Then the Holy One, blessed be He, had to reveal Himself to him and show him that He is the Owner of the city. And regarding this matter, it says, "When a woman conceives," because there is no value in the term "woman" in the world of nobility, as is explained in the Gemara (Shabbat 88a): "What is the significance of a female birth among us?" And it is said, "When a woman conceives," etc. That is, one who has a true desire with strength and vigor for the Holy One, blessed be He, and gives birth to a male child, and he is the one who clearly achieves true salvation. For the birth of a male indicates true salvation because all the good is included in the soul of the Jewish person. And this is the matter of the Midrash: "We calculate for the sake of our forefather Abraham." That is, Abraham recognized from himself that there is a leader in the world, and we too can recognize when we turn our minds to Abraham to contemplate his ways, for the awakening of Abraham's heart caused amazement to everyone who understood why he was awakened in his heart to inquire and wonder who created the world and its fullness, and how many thousands of souls were before, and it did not occur to them to ask this. From this awakening itself, we can understand that there is a Creator and Leader, for the desire that came to Abraham's heart was also from what the Holy One, blessed be He, sent to him in his heart. For if this had happened naturally, why did it not happen to all the world? And this is what the Midrash says: "We calculate for the sake of our forefather Abraham," for his name indicates his will, as is found in people who are called by their actions and professions because all their will is in the matter they are involved in. And also his name in the Gemara is will. And this is "I will bring forth My righteousness from afar," for His name indicates His will, as found in people who are called by their actions and professions, for their entire will is in the matter they are involved in, and His name in the Gemara is will.
Tiferet Shlomo
*The women who will conceive and give birth to a male:* why doesn't it mention the seed? It says in the Torah "just like the land produces its produce and like the garden produces its produce so does G-d cause righteousness to sprout." If you plant something in the ground, the ground accepts the seed and, if it doesn't get ruined, it will certainly grow without a doubt. In a similar way, we pray for the sprouting of the Redemption, the coming of Moshiach speedily in our days. As it says in davening: "Moshiach should come." We also say in our prayer "Let the glory of Dovid your servant sprout." It also says "there's a man who's named is Tzemach" that's a reference to Moshiach. Why is Moshiach associated with growth and sprouting? The name of Moshiach existed before the world. So, too, G-d created Heaven and Earth and then there was Light and that light is the light of Moshiach. The original light that Hashem is planted and from that time it came to the world, from before, to grow and sprout our Moshiach, he come speedily in our days. Because of the generous rain and prayer and tears, asking for Moshiach, causes the light to continually grow. All of the prophets who prophesized about Moshiach use the present and past tense. This is because the growth of Moshiach happens every day, which is why the Tanach uses present and past tense. As it says "the first one to Zion, behold, behold them, and for Jerusalem I will give a herald" Yeshaya 41:27 [https://www.chabad.org/library/bible_cdo/aid/15972/jewish/Chapter-41.htm]. We are asking to speedily see the growth and greatness of Moshiach when he is revealed, may it happen speedily. That's why we say in our prayers "let our salvation quickly sprout and may agony and sighing depart from us." Even in our time, when Moshiach hasn't come, there should be growth in the light of Moshiach to feel some of the effects of Redemption. This is the meaning of the posuk "just like the earth produces it produce so will G-d cause righteousness to sprout." The similarity is that when seed is in the ground and not ruined, the growth is guaranteed; so too, with the light of Moshiach, it is certain it will sprout. This is the meaning of the posuk "the woman who gave seed gives birth to a boy." What this means "when a women seeds, and she receives the seed in a proper way" that when the Jewish people put in effort to become closer to G-d then the offspring is male. Male is associated with mercy and through this the good deeds of the Jewish people cause the elevation of the female waters properly and they draw down kindness and mercy upon the Jewish people in this world.
Rashi
אשה כי תזריע IF A WOMAN HAVE CONCEIVED SEED — R. Simlai said: Even as the formation of man took place after that of every cattle, beast and fowl when the world was created, so, too, the law regarding him is set forth after the law regarding cattle, beast and fowl (contained in the previous chapter) (Leviticus Rabbah 14:1).
