וַיִּסְע֖וּ מֵרְפִידִ֑ם וַֽיַּחֲנ֖וּ בְּמִדְבַּ֥ר סִינָֽי׃
И отправились они из Рефидима и расположились в пустыне Синайской.
Mekhilta DeRabbi Yishmael
(Ibid. 2) "And they journeyed from Refidim and they came to the desert of Sinai": Is it not already written (Ibid. 1) "they came to the desert of Sinai"? — Their journeying from Refidim is being likened to their coming to the desert of Sinai. Just as the latter was in a state of repentance, so, the former.
