Allegorically the question was asked "And where did Mount Sinai come from?" Rabbi Yosi said (Midrash Tehilim Mizmor 68) ’it was separated from Mount Moriah, like the hallah* offering from the dough, from the place where Yitzchak, our father was bound. The Holy One said – since Yitzchak was bound upon it, it is fitting that his children receive the Torah upon it. (*dough is separated from the bread baked for Sabbath and burned)
Yitzchak or Isaac was 37 years at his binding. King David returned Moses Ark of the Covenant to Israel, to the City of David, Jerusalem where it was located for 37 years until his son Solomon moved it to its more permanent place in the Holy of Holies of the First Temple.
