וַיִּפְגַּ֨ע בַּמָּק֜וֹם וַיָּ֤לֶן שָׁם֙ כִּי־בָ֣א הַשֶּׁ֔מֶשׁ וַיִּקַּח֙ מֵאַבְנֵ֣י הַמָּק֔וֹם וַיָּ֖שֶׂם מְרַֽאֲשֹׁתָ֑יו וַיִּשְׁכַּ֖ב בַּמָּק֥וֹם הַהֽוּא׃
한곳에 이르러는 해가 진지라 거기서 유숙하려고 그곳의 한 돌을 취하여 베개하고 거기 누워 자더니
Pri HaAretz
It is written in the Midrash "Taking one of the stones of that place", in the beginning there were many stones and for Jacob they became one stone. And it is therefore said "[Jacob] took the stone" (see there).
Rashi on Genesis
ויפגע במקום AND HE LIGHTED UPON THE PLACE — Scripture does not mention which place, but by writing בַּמָקוֹם the place it refers to the place mentioned already in another passage, viz., Mount Moriah of which it is stated (Genesis 22:4) “And he saw the place (המקום) afar off”.
Rashbam on Genesis
ויפגע במקום, on his way he had an encounter in or near a town known as Luz.
