Rashi on Numbers 23:3/רש"י על במדבר כ״ג:ג׳

1'אולי יקרה ה‎‎ לקראתי PERHAPS THE LORD WILL HAPPEN TO MEET ME — Perhaps: He is not accustomed to speak with me by day.

2וילך שפי AND HE WENT שפי — Understand this as the Targum does: “alone”; it is an expression denoting ease and tranquillity; the statement means that there was nothing with him except silence (nothing to disturb him).
