Exodus 18:26

וַיִּשְׁמַע מֹשֶׁה לְקוֹל חֹתְנוֹ וַיַּעַשׂ כֹּל אֲשֶׁר אָמָֽר

So Moses hearkened to the voice of his father-in-law, and did all that he had said.

וַיִּבְחַר מֹשֶׁה אַנְשֵׁי־חַיִל מִכָּל־יִשְׂרָאֵל וַיִּתֵּן אֹתָם רָאשִׁים עַל־הָעָם שָׂרֵי אֲלָפִים שָׂרֵי מֵאוֹת שָׂרֵי חֲמִשִּׁים וְשָׂרֵי עֲשָׂרֹֽת

And Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens.

וַיְשַׁלַּח מֹשֶׁה אֶת־חֹתְנוֹ וַיֵּלֶךְ לוֹ אֶל־אַרְצֽוֹ

And Moses let his father-in-law depart; and he went his way into his own land.

בַּחֹדֶשׁ הַשְּׁלִישִׁי לְצֵאת בְּנֵי־יִשְׂרָאֵל מֵאֶרֶץ מִצְרָיִם בַּיּוֹם הַזֶּה בָּאוּ מִדְבַּר סִינָֽי

In the third month after the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai.
