Rashi Teaches:
“When Yaakov passed the place of the Temple why did He not make him stop there?” — If it never entered his mind to pray at the spot where his fathers had prayed should Heaven detain him there? Really he had reached as far as Haran as we say in the chapter Gid Hanasheh (Chullin 91b), and Scripture itself proves this since it states, “And he went to Haran”.
When he arrived at Haran he said, “Is it possible that I have passed the place where my fathers prayed without myself praying there?” He decided to return and got as far as Bet-el when the journey was shortened for him (lit. “the land jumped for him”). This Bet-el is not the Bet-el that is near Ai (cf. Genesis 12:8) but that which is near Jerusalem, and because he said of it, “It shall be the House of the L-rd”, he called it Bet-el. This, too, is Mount Moriah, where Avraham prayed, and it is also the field in which Yitzchak offered prayer as it is written, “[Yitzchak went out] to talk (i. e., to pray; cf. Genesis 24:63) in the field”. For thus, too, do we say in Tractate Pesachim (88a) in a comment on the verse (Micah 4:2): “Go out and let us ascend to the mountain of Hashem and to the house of the L-rd of Yaakov”. Why is Yaakov singled out? Rather, not as Avraham who called it a mount, as it is written in the mountain of Hashem, he will appear (Genesis 22:14) and not as Yitzchak, who called it a field, as it is written to “talk in the field” (Genesis 24:63), but as Yaakov did, who called it a house.
