Rashi on I Samuel
By Rochel's Tomb, at the border of Binyomin. Isn't Rochel's Tomb within Yehudah's border, in Beis Lechem? [The answer is that] they are now by Rochel's Tomb, but, 'when you will meet them, you will find them within Binyomin's border, in Tzeltzoch.' Thus was taught by the Tosefta of [Maseches] Sotah.111:7.
Rashi on I Samuel
Tzeltzoch is a combination of the words צֵל לַצַּח of the Holy One, Blessed is He, Who is pure and ruddy;2Shir Hashirim 5:10. and this is Yerusholayim.
Rashi on I Samuel
And is worrying about you. Has fears concerning you; every expression of דְּאָגָה [worry] is an expression of fear; dementer in O.F.
