וַיְבָ֤רֶךְ אֱלֹהִים֙ אֶת־י֣וֹם הַשְּׁבִיעִ֔י וַיְקַדֵּ֖שׁ אֹת֑וֹ כִּ֣י ב֤וֹ שָׁבַת֙ מִכָּל־מְלַאכְתּ֔וֹ אֲשֶׁר־בָּרָ֥א אֱלֹהִ֖ים לַעֲשֽׂוֹת׃ (פ)
Благословил Бог седьмой день и освятил его, ведь в этот день прекратил Он все труды, которыми [Он], Бог, занимался.
Rashi
ויברך … ויקדש AND GOD BLESSED … AND HE SANCTIFIED — He blessed it through the Manna, that on all other days of the week there should fall for them (the Israelites) an Omer for each person, whereas on the sixth day there should fall twice as much of that bread. So, too, He sanctified it through the Manna, that it should not fall at all on the Sabbath (Genesis Rabbah 11:2). This verse is written here with reference to what would happen in the future.
Aderet Eliyahu
[...] "from all His work that God created to do/make." The explanation of this is that "to do/make" refers to the future. That is that the Holy-One-blessed-be-He renews every day anew the work of creation. And the renewal of the work of creation on the Sabbath day is prepared on the day before and on the Sabbath He refrains from that too; and that is the meaning of what is said "from all."
Chizkuni
ויברך אלוקים את יום השביעי, “G-d blessed the seventh day.”[If I understand the author correctly, he does not understand the word ויברך here as in the immediate past, but as description of the state of the universe on that day as a result of its Creator having blessed it previously. Ed.] On this day the world was in a state of perfection full of everything positive, and fully satisfied. Compare Deuteronomy 5,14: אשר ברכך ה' אלוקיך תתן לו, “that the Lord your G-d has blessed you with, give him of it.” (the departing servant). This is also what we recite regularly in our prayers: “You have blessed it more than any other days.”
