(11) Who is like You, O LORD, among everything which is worshipped; who is like You, majestic in holiness, awesome in splendor, working wonders!

(18) The LORD will reign for ever and ever!

(3) You were always the help of our ancestors, a shield for them and their children, our deliverer in every generation. Though You abide at the pinnacle of the universe, Your just decrees extend to the ends of the earth. Happy the one who obeys Your mitzvot, who takes to heart the words of Your Torah. You are, in truth, a mentor to Your people, their defender and mighty Ruler. You are first and You are last; we have no Sovereign or Redeemer but You. You rescued us from Egypt, and redeemed us from the house of bondage. The firstborn of the Egyptians were slain; Your firstborn were saved. You split the waters of the sea. The faithful You rescued; the wicked drowned. The waters engulfed Israel's enemies; not one of the arrogant remained alive. Then Your beloved sang hymns of acclamation, extolling you with psalms of adoration. They acclaimed G-d Sovereign, great and awesome Source of all blessing, the everliving G-d, exalted in all majesty. G-d humbles the proud and raises the lowly, frees the captive and redeems the meek. G-d helps the needy and answers G-d's people's call. Praises to G-d supreme, who is ever praised. Moses and the people Israel joyfully sang this song to you. "Who is like you, Adonai, among all that is worshipped! Who is, like You, majestic in holiness, awesome in splendor, working wonders!" The redeemed sang a new song for You. They sang in chorus at the shore of the sea, acclaiming Your sovereignty: "Adonai shall reign throughout all time." Rock of Israel, arise to Israel's defense. Fulfill Your promise to deliver Judah and Israel. Our Redeemer is the Holy One of Israel, Adonai Tz'va-ot. Praised are You, Adonai, Redeemer of the people Israel.

The Gemara comments: As Rabbi Shmuel bar Naḥman says that Rabbi Yonatan says: What is the meaning of that which is written in the passage describing the splitting of the Red Sea: “And the one came not near the other all the night” (Exodus 14:20)? At that time the ministering angels desired to recite a song before the Holy One, Blessed be He. The Holy One, Blessed be He, said to them: My handiwork, i.e., the Egyptians, are drowning in the sea, and you are reciting a song before Me? Apparently, God is not gladdened by the downfall of the wicked.

(21) Elijah approached all the people and said, “How long will you keep hopping between two opinions? If the LORD is God, follow Him; and if Baal, follow him!” But the people answered him not a word.

(1) Then Moses and the Israelites sang this song to the LORD. They said: I will sing to the LORD, for He has triumphed gloriously; Horse and driver He has hurled into the sea.(2) The LORD is my strength and might; He is become my deliverance. This is my God and I will enshrine Him; The God of my father, and I will exalt Him.(3) The LORD, the Warrior— LORD is His name!(4) Pharaoh’s chariots and his army He has cast into the sea; And the pick of his officers Are drowned in the Sea of Reeds.(5) The deeps covered them; They went down into the depths like a stone.(6) Your right hand, O LORD, glorious in power, Your right hand, O LORD, shatters the foe!(7) In Your great triumph You break Your opponents; You send forth Your fury, it consumes them like straw.(8) At the blast of Your nostrils the waters piled up, The floods stood straight like a wall; The deeps froze in the heart of the sea.(9) The foe said, “I will pursue, I will overtake, I will divide the spoil; My desire shall have its fill of them. I will bare my sword— My hand shall subdue them.”(10) You made Your wind blow, the sea covered them; They sank like lead in the majestic waters.(11)Who is like You, O LORD, among the celestials; Who is like You, majestic in holiness, Awesome in splendor, working wonders!(12) You put out Your right hand, The earth swallowed them.(13) In Your love You lead the people You redeemed; In Your strength You guide them to Your holy abode.(14) The peoples hear, they tremble; Agony grips the dwellers in Philistia.(15) Now are the clans of Edom dismayed; The tribes of Moab—trembling grips them; All the dwellers in Canaan are aghast.(16) Terror and dread descend upon them; Through the might of Your arm they are still as stone— Till Your people cross over, O LORD, Till Your people cross whom You have ransomed.(17) You will bring them and plant them in Your own mountain, The place You made to dwell in, O LORD, The sanctuary, O LORD, which Your hands established.(18)The LORD will reign for ever and ever!

(4) In the morning one recites two blessings before it (the Shema) ["yotzer or" and "ahavah rabba"], and one after it ["emet veyatziv"]; in the evening two before it ["ma'ariv aravim" and “ahavat olam"] and two after it ["emet ve'emunah" and presumably "hashkiveinu"], one long and one short. ...

According to Rabbi Yoḥanan, it is a mitzva to recite Shema before the evening prayer (Amidah). Mar, son of Ravina, raises an objection from a mishna: How can one do that? We learn in a later mishna: In the evening, one recites two blessings prior to the recitation of Shemaand two blessings afterward. And if you say that one must juxtapose redemption (Mi Chamocha) to prayer (Amidah), doesn’t one fail to juxtapose redemption (Mi Chamocha) to prayer (Amidah), as one must recite: Help us lie down [hashkivenu], the blessing recited after the blessing of redemption (Mi Chamocha), which constitutes an interruption between redemption (Mi Chamocha) and prayer (Amidah)?They say in response: Since the Sages instituted the practice of reciting: Help us lie down (Hashkiveinu), it is considered one extended blessing of redemption, and therefore does not constitute an interruption.

(17) The order of the prayers is as follows. In the morning, ...When he has concluded the blessing after the Shema, which closes with the phrase, "Who redeemedst Isael" he immediately rises, so that the reference to the Redemption may be connected with the Amidah prayer, which, as already stated by us, is recited standing. ...
(18) ... In the evening service, the worshipper reads the Shema, reciting the appropriate blessings before and after it. The blessing referring to the redemption of Israel is connected with the Amidah, which is recited, standing. ... Though the blessing concluded, "Who redeemedst Israel" is followed by the blessing beginning, "Cause us to lie down", this is not regarded as an interruption between the blessing relating to redemption and the Amidah, both blessings being regarded as one lengthy blessing.

In the Talmud, Rabbi Yochanan says that one needs to follow the evening G'ulah directly with the evening T'filah. We might see Hashkiveinu as a pause, but instead we should see it as an extension of the G'ulah. We should view it just like the preface "Adonai S'fatai, Open my lips," which was instituted as a part of the T'filah. We see Hashkiveinu as an extension of the G'ulah in that when G-d plagued Egypt, G-d caused a great fear upon the people [amidst the darkness]. They prayed to the Holy One, that the Angel of Death would not come to their houses to inflict death upon them. Hashkiveinu is a reminder of the fear the Israelites faced during the time of redemption; therefore it is a part of the ​G'ulah

(1) One needs to join “redemption” to “prayer”. And he should not interrupt between them, even for the Amen after “Ga’al Yisael” and not for any verse other than “Hashem Sefosai”. COMMENT: And some say that it is permitted to respond Amen on “Ga’al Yisael”, and so is our custom. And some say that this rule to juxtapose “redemption” to “prayer” is only on a weekday or holiday. But on Shabbos he does not need to. (Meaning, that the reason that we require to juxtapose “redemption” to “prayer” I because it is written “God will answer you in a day of distress,” and near it, “Let the words of my mouth be desire … and my redeemer.” And Shabbos is not a period of distress. And in my humble opinion, this doesn’t apply on a holiday because they are days of judgement, as we learned in the Mishna in Rosh HaShana 1:2, “On Passover regarding grain…”) And it is good to be stringent unless in a place of need.

Who is like You, O God, among the gods who are worshipped?
Who is like You, majestic in holiness, awesome in splendor, working wonders?

With new song, inspired at the shore of the Sea, the redeemed sang Your praise.
In unison the all offered thanks, acknowledging Your sovereignty they said: "Adonai will reign forever."

Rock of Israel, rise in support of Israel and redeem Judah and Israel as You promised.
Our Redeemer, Adonai Tz'vatot is Your Name.
Blessed are You, Adonai, for redeeming Israel.
