Quoting Commentary for I Samuel 2:2

And Channah prayed and said: She prayed before the Lord and gave Him praise and thanksgiving for the son that He gave her. And she prayed to the Lord that he would live and that he would be for the Lord. And Yonatan translated it [in the Targum] as, "And Channah prayed with a spirit of prophecy and said, 'Shmuel, my son, will be a prophet over Israel in the future, etc.'" And Yonatan also translated this song [to be] about the kings of the nations of the world and about the congregation of Israel. And about the verse, "There is no holy one like the Lord" (I Samuel 2:2), he said, "About Sancheriv, the king of Assyria, she prophesied and said." And about the verse, "Do not abound with speech" (I Samuel 2:3), he said, "About Nevuchadnetzar, the king of Babylonia, she prophesied and said." And about the verse, "The bows of the mighty are broken" (I Samuel 2:4), he said, "About the kingdom of Antiochus, she prophesied and said." And about the verse, "The sated, for bread" (I Samuel 2:5), he said, "About the sons of Haman, she prophesied and said." And about the verse, "The Lord kills, and gives life" (I Samuel 2:6) until, "O Lord, may His adversaries be shattered" (I Samuel 2:10), he spoke about the reward of the righteous in the Garden of Eden and the punishment of the wicked in Geihinnom. And in the verse, "O Lord, may His adversaries be shattered," she spoke [about] the judgement of Gog and Magog and the kingdom of our Messiah. But according to the simple meaning, Channah opened this song, with regards to those tranquil in the world and the proud ones; and about the humble ones of the earth and the lowly ones - that the Holy One, blessed be He, sees everything. So 'He brings down the proud and raises the lowly' - like the thing that was upon her and upon Peninah, her rival.

באחד לחודש השני, “on the first of the second month.” The subject matter of G’d’s conversation with Moses at that time was the details of the encampment, the positioning of the flags, in which order the people should break camp and in which order they should make camp. (this needs elaboration as a) our portion does not contain any of the 613 commandments, b) the Jewish people did not start journeying until the twenty-second of that month). The reason why this portion follows the chapter dealing with the laws about exchanging the objects of vows made (Leviticus 27), is to remind us that G’d is One, is Unique, and there are no substitutes for Him. Just as there are no substitutes for G’d, so there is no substitute for the unique Jewish people and He will never exchange us for any other nation. We have this on the authority of Song of Songs 2,16 דודי לי ואני לו, “My beloved belongs to me and I to Him.” We also have a verse spelling out the other half of this relationship when we read in Samuel I 2,3 (Chanah speaking) אין קדוש כה' ואין בלתך, “there is none as holy as G’d and there is none beside You.” Furthermore, we find that the Jewish people are referred to as G’d’s “flock” in Ezekiel 34,31. Just as we learned in the last chapter of Leviticus that no member of the flock once it has been sanctified must be exchanged, so we may rest assured that G’d will never exchange His flock, i.e. the Jewish people.

Bahya further writes and also Toldot Yizhak. Why is the portion of Bamidbar, which talks about the number of Israelites, written near the portion of Behukotai, which talks about not exchanging a good animal for a bad animal for the sacrifices? This teaches us that He is the only one in all the worlds, and is never exchanged, as the verse says, “there is no holy one like the Lord, truly, there is none better besides You” [I Samuel, 2:2]. Similarly, the Holy One will not exchange Israel for any other nation. The Midrash writes. The Holy One said: to no nation have I given a number of how many of them there are. However, to you Israel, I have given a number of how many there are. It is a parable. A king has a barn full of straw. He does not count how much straw he has. Then he has another barn with wheat. He says to his chief assistant, count how much wheat is in the barn. This parable shows the king as the Holy One and the barn is His Israel, as the verse says, “My threshing, the product of my threshing floor” [Isaiah, 21:10]. That is, Israel is compared to a barn, and is compared to a holy grain, as the verse says, “Israel was holy to the Lord, the first fruits of His harvest” [Jeremiah, 2:3]. The Holy One said to Moses Our Teacher, who is the overseer of the Holy One’s house, as the verse says, “he is trusted throughout My household” [Numbers, 12:7]. Moses counts how many Israelites there are. The nations of the world are compared to straw, as the verse says, “let them become like straw in the wind” [Job, 21:18]. They will be like straw in the wind.³Bahya, Numbers, 1:1; Toldot Yizhak, Numbers, 1:1–4.

הלבן SHALL A CHILD BE BORN TO ONE WHO IS A HUNDRED YEARS OLD? — There are some questions expressing astonishment which do not imply a doubt but rather affirm the certainty that the circumstance referred to has happened or will happen, as (1 Samuel 2:2) “Did I reveal myself [unto thy father’s house?]” (Of course, I did) and (Ezekiel 8:6) “Seest thou what they do?” (You, of course, have seen it). This question, too, affirms the certainty that it is possible for God to cause Abraham, at the age of hundred, to beget a son and this is in effect what he said to himself: Would there be done to another man one hundred years old this favour that the Holy One, blessed be He, is doing to me”? (Rashi means that the words must be translated, “would a child be born to any other person who is a hundred years old?”).
