Exodus 16:2

וַיָּבֹאוּ אֵילִמָה וְשָׁם שְׁתֵּים עֶשְׂרֵה עֵינֹת מַיִם וְשִׁבְעִים תְּמָרִים וַיַּחֲנוּ־שָׁם עַל־הַמָּֽיִם

And they came to Elim, where were twelve springs of water, and three score and ten palm-trees; and they encamped there by the waters.

וַיִּסְעוּ מֵֽאֵילִם וַיָּבֹאוּ כָּל־עֲדַת בְּנֵֽי־יִשְׂרָאֵל אֶל־מִדְבַּר־סִין אֲשֶׁר בֵּין־אֵילִם וּבֵין סִינָי בַּחֲמִשָּׁה עָשָׂר יוֹם לַחֹדֶשׁ הַשֵּׁנִי לְצֵאתָם מֵאֶרֶץ מִצְרָֽיִם

And they took their journey from Elim, and all the congregation of the children of Israel came unto the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departing out of the land of Egypt.

וַיֹּאמְרוּ אֲלֵהֶם בְּנֵי יִשְׂרָאֵל מִֽי־יִתֵּן מוּתֵנוּ בְיַד־יְהוָה בְּאֶרֶץ מִצְרַיִם בְּשִׁבְתֵּנוּ עַל־סִיר הַבָּשָׂר בְּאָכְלֵנוּ לֶחֶם לָשֹׂבַע כִּֽי־הוֹצֵאתֶם אֹתָנוּ אֶל־הַמִּדְבָּר הַזֶּה לְהָמִית אֶת־כָּל־הַקָּהָל הַזֶּה בָּרָעָֽב

and the children of Israel said unto them: ‘Would that we had died by the hand of the LORD in the land of Egypt, when we sat by the flesh-pots, when we did eat bread to the full; for ye have brought us forth into this wilderness, to kill this whole assembly with hunger.’

וַיֹּאמֶר יְהוָה אֶל־מֹשֶׁה הִנְנִי מַמְטִיר לָכֶם לֶחֶם מִן־הַשָּׁמָיִם וְיָצָא הָעָם וְלָֽקְטוּ דְּבַר־יוֹם בְּיוֹמוֹ לְמַעַן אֲנַסֶּנּוּ הֲיֵלֵךְ בְּתוֹרָתִי אִם־לֹֽא

Then said the LORD unto Moses: ‘Behold, I will cause to rain bread from heaven for you; and the people shall go out and gather a day’s portion every day, that I may prove them, whether they will walk in My law, or not.
