We read Vaykhulu three times on the Shabbat eve, which includes the verse Bereishit 2:3:
וַיְבָ֤רֶךְ אֱלֹהִים֙ אֶת־י֣וֹם הַשְּׁבִיעִ֔י וַיְקַדֵּ֖שׁ אֹת֑וֹ כִּ֣י ב֤וֹ שָׁבַת֙ מִכָּל־מְלַאכְתּ֔וֹ אֲשֶׁר־בָּרָ֥א אֱלֹהִ֖ים לַֽעֲשֽׂוֹת׃
And Hashem blessed the seventh day, and hallowed it; because that in it He rested from all His work which Hashem in creating had made.
What is the relevance of having these two similar words in the sentence? Do commentators expound upon this difference?
