After swearing an oath to Zoram that he would be safe if he went with them to the tent of their father Lehi, Nephi makes an interesting statement: "Now we were desirous that he should tarry with us for this cause, that the Jews might not know concerning our flight into the wilderness, lest they should pursue us and destroy us" (1 Nephi 4:36).
Brant Gardner asks, How could Zoram have known where to find Lehi? It appears that Lehi followed fairly well known and traveled trade routes for at least the early part of his journey. Having left a particular gate of Jerusalem, the direction to the trade route may have been obvious.
