This prayer is often referred to as the repetition of the Shabbat evening amidah, or as Magen Avot, Shield of our Ancestors 

וַיְכֻלּוּ הַשָּׁמַֽיִם וְהָאָֽרֶץ וְכָל צְבָאָם. וַיְכַל אֱלֹהִים בַּיּוֹם הַשְּׁבִיעִי מְלַאכְתּוֹ אֲשֶׁר עָשָׂה, וַיִּשְׁבֹּת בַּיּוֹם הַשְּׁבִיעִי, מִכָּל מְלַאכְתּוֹ אֲשֶׁר עָשָׂה. וַיְבָֽרֶךְ אֱלֹהִים אֶת יוֹם הַשְּׁבִיעִי וַיְקַדֵּשׁ אֹתוֹ, כִּי בוֹ שָׁבַת מִכָּל מְלַאכְתּוֹ, אֲשֶר בָּרָא אֱלֹהִים לַעֲשׂוֹת.

And the Heaven and the Earth were finished and all their host. And on the seventh day God finished working and rested from all the work which had been made. And God blessed the seventh day, and hallowed it through rest from all the work which God had created and made.

בָּרוּךְ אַתָּה יְיָ, אֱלֹהֵֽינוּ וֵאלֹהֵי אֲבוֹתֵֽינוּ וְאִמּוֹתֵינוּ, אֱלֹהֵי אַבְרָהָם, אֱלֹהֵי יִצְחָק, וֵאלֹהֵי יַעֲקֹב, אֱלֹהֵי שָּׂרָה, אֱלֹהֵי רִבְקָה, אֱלֹהֵי לֵאָה וֵאלֹהֵי רָחֵל, הָאֵל הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא, אֵל עֶלְיוֹן, קוֹנֵה שָׁמַֽיִם וָאָֽרֶץ.

Blessed are You, Adonai our God and God of our fathers and mothers, God of Abraham, God of Isaac, and God of Jacob, God of Sarah, God of Rebecca, God of Leah, and God of Rachel, the great, mighty and revered God, the most High God, Master of heaven and earth.

. מָגֵן אָבוֹת וְאִמָּהוֹת בִּדְבָרוֹ, מְחַיֵּה הַכֹּל בְּמַאֲמָרוֹ, הָאֵל הַקָּדוֹשׁ שֶׁאֵין כָּמֽוֹהוּ, הַמֵּנִֽיחַ לְעַמּוֹ בְּיוֹם שַׁבַּת קָדְשׁוֹ, כִּי בָם רָצָה לְהָנִֽיחַ לָהֶם. לְפָנָיו נַעֲבוֹד בְּיִרְאָה וָפַֽחַד, וְנוֹדֶה לִשְׁמוֹ בְּכָל יוֹם תָּמִיד, מֵעֵין הַבְּרָכוֹת. אֵל הַהוֹדָאוֹת, אֲדוֹן הַשָּׁלוֹם, מְקַדֵּשׁ הַשַּׁבָּת וּמְבָרֵךְ שְׁבִיעִי, וּמֵנִֽיחַ בִּקְדֻשָּׁה לְעַם מְדֻשְּׁנֵי עֹֽנֶג, זֵֽכֶר לְמַעֲשֵׂה בְרֵאשִׁית.

God’s words were a shield to our ancestors. Our holy God, like which nothing can compare, gives rest to us--God’s people--on this holy Sabbath day, because God took pleasure in us and granted us rest. We will serve Adonai with reverence and awe, and daily and constantly we will give thanks through our blessings. It is to God alone our thanksgivings are due, the Sovereign of peace, who hallows the Sabbath and blesses the seventh day, and in holiness gives rest to a people content with delight, in remembrance of the creation.
