Sforno on Numbers 22:38/ספורנו על במדבר כ״ב:ל״ח

1הנה באתי אליך, even though I would have come to you at the time as you requested, what good would it have done you? Even now the situation is the same.

2?היכול אוכל דבר מאומה; I am totally unable to speak in the manner normal people speak when they express their own will. הדבר אשר ישים אלוקים בפי אותו אדבר, similar to Samuel II 23,2 where David said that the spirit of the Lord spoke through him, i.e. רוח ה' דיבר בי. When uttering words in this fashion I am truly not the speaker.
