Exodus 4:1

וְנָתַתִּי אֶת־חֵן הָֽעָם־הַזֶּה בְּעֵינֵי מִצְרָיִם וְהָיָה כִּי תֵֽלֵכוּן לֹא תֵלְכוּ רֵיקָֽם

And I will give this people favour in the sight of the Egyptians. And it shall come to pass, that, when ye go, ye shall not go empty;

וְשָׁאֲלָה אִשָּׁה מִשְּׁכֶנְתָּהּ וּמִגָּרַת בֵּיתָהּ כְּלֵי־כֶסֶף וּכְלֵי זָהָב וּשְׂמָלֹת וְשַׂמְתֶּם עַל־בְּנֵיכֶם וְעַל־בְּנֹתֵיכֶם וְנִצַּלְתֶּם אֶת־מִצְרָֽיִם

but every woman shall ask of her neighbour, and of her that sojourneth in her house, jewels of silver, and jewels of gold, and raiment; and ye shall put them upon your sons, and upon your daughters; and ye shall spoil the Egyptians.’

וַיֹּאמֶר אֵלָיו יְהוָה מזה בְיָדֶךָ וַיֹּאמֶר מַטֶּֽה

And the LORD said unto him: ‘What is that in thy hand?’ And he said: ‘A rod.’

וַיֹּאמֶר הַשְׁלִיכֵהוּ אַרְצָה וַיַּשְׁלִיכֵהוּ אַרְצָה וַיְהִי לְנָחָשׁ וַיָּנָס מֹשֶׁה מִפָּנָֽיו

And He said: ‘Cast it on the ground.’ And he cast it on the ground, and it became a serpent; and Moses fled from before it.
