שמואל א, י  

(ב)   בְּלֶכְתְּךָ הַיּוֹם, מֵעִמָּדִי, וּמָצָאתָ שְׁנֵי אֲנָשִׁים עִם-קְבֻרַת רָחֵל בִּגְבוּל בִּנְיָמִן, בְּצֶלְצַח; וְאָמְרוּ אֵלֶיךָ, נִמְצְאוּ הָאֲתֹנוֹת אֲשֶׁר הָלַכְתָּ לְבַקֵּשׁ, וְהִנֵּה נָטַשׁ אָבִיךָ אֶת-דִּבְרֵי הָאֲתֹנוֹת, וְדָאַג לָכֶם לֵאמֹר מָה אֶעֱשֶׂה לִבְנִי.

Shmuel 1, 10 

(2)   When thou art departed from me to-day, then thou shalt find two men by the tomb of Rachel, in the border of Benjamin at Zelzah; and they will say unto thee: The asses which thou wentest to seek are found; and, lo, thy father hath left off caring for the asses, and is anxious concerning you, saying: What shall I do for my son?

Yermiyahu 31 

 (14)   Thus said Hashem: A voice is heard in Ramah, lamentation, and bitter weeping, Rachel weeping for her children; she refuses to be comforted for her children, because they are not.
(15)   Thus said Hashem: Refrain thy voice from weeping, and thy eyes from tears; for thy work shall be rewarded, said Hashem; and they shall come back from the land of the enemy.
(16)   And there is hope for thy future, said Hashem; and thy children shall return to their own border.
