וַיִּשְׁלַ֤ח יְהוָה֙ אֶת־יָד֔וֹ וַיַּגַּ֖ע עַל־פִּ֑י וַיֹּ֤אמֶר יְהוָה֙ אֵלַ֔י הִנֵּ֛ה נָתַ֥תִּי דְבָרַ֖י בְּפִֽיךָ׃
און גאָט האָט אױסגעשטרעקט זײַן האַנט און צוגערירט, צו מײַן מױל, און גאָט האָט צו מיר געזאָגט:אָט האָב איך געגעבן מײַנע װערטער אין דײַן מױל;
Tze'enah Ure'enah
“And the Lord put out His hand and touched, etc.” [1:9]. God put His hand on my mouth and God said to me, I have put My words in your mouth.
Rashi
And the Lord stretched forth His hand Every sending mentioned concerning a hand is an expression of stretching forth. Another explanation is like the Targum: And the Lord sent the words of His prophecy.
