וַֽנִּסְעָ֞ה מִנְּהַ֣ר אַֽהֲוָ֗א בִּשְׁנֵ֤ים עָשָׂר֙ לַחֹ֣דֶשׁ הָרִאשׁ֔וֹן לָלֶ֖כֶת יְרוּשָׁלִָ֑ם וְיַד־אֱלֹהֵ֙ינוּ֙ הָיְתָ֣ה עָלֵ֔ינוּ וַיַּ֨צִּילֵ֔נוּ מִכַּ֥ף אוֹיֵ֛ב וְאוֹרֵ֖ב עַל־הַדָּֽרֶךְ׃
Then we departed from the river of Ahava on the twelfth day of the first month, to go unto Jerusalem; and the hand of our God was upon us, and He delivered us from the hand of the enemy and lier-in-wait by the way.
Rashi on Ezra
the hand of our God was upon us to cause us to succeed in the way that we traversed.
