1 Samuel 1:10

וַיֹּאמֶר לָהּ אֶלְקָנָה אִישָׁהּ חַנָּה לָמֶה תִבְכִּי וְלָמֶה לֹא תֹֽאכְלִי וְלָמֶה יֵרַע לְבָבֵךְ הֲלוֹא אָֽנֹכִי טוֹב לָךְ מֵעֲשָׂרָה בָּנִֽים

And Elkanah her husband said unto her: ‘Hannah, why weepest thou? and why eatest thou not? and why is thy heart grieved? am not I better to thee than ten sons?’

וַתָּקָם חַנָּה אַחֲרֵי אָכְלָה בְשִׁלֹה וְאַחֲרֵי שָׁתֹה וְעֵלִי הַכֹּהֵן יֹשֵׁב עַל־הַכִּסֵּא עַל־מְזוּזַת הֵיכַל יְהוָֽה

So Hannah rose up after they had eaten in Shiloh, and after they had drunk—now Eli the priest sat upon his seat by the door-post of the temple of the LORD;

וַתִּדֹּר נֶדֶר וַתֹּאמַר יְהוָה צְבָאוֹת אִם־רָאֹה תִרְאֶה בָּעֳנִי אֲמָתֶךָ וּזְכַרְתַּנִי וְלֹֽא־תִשְׁכַּח אֶת־אֲמָתֶךָ וְנָתַתָּה לַאֲמָתְךָ זֶרַע אֲנָשִׁים וּנְתַתִּיו לַֽיהוָה כָּל־יְמֵי חַיָּיו וּמוֹרָה לֹא־יַעֲלֶה עַל־רֹאשֽׁוֹ

And she vowed a vow, and said: ‘O LORD of hosts, if Thou wilt indeed look on the affliction of Thy handmaid, and remember me, and not forget Thy handmaid, but wilt give unto Thy handmaid a man-child, then I will give him unto the LORD all the days of his life, and there shall no razor come upon his head.’

וְהָיָה כִּי הִרְבְּתָה לְהִתְפַּלֵּל לִפְנֵי יְהוָה וְעֵלִי שֹׁמֵר אֶת־פִּֽיהָ

And it came to pass, as she prayed long before the LORD, that Eli watched her mouth.
