Matthew Poole and continuators on Genesis 28:15

15 And behold, I am with thee, and will keep thee in all places whither thou goest, and will bring thee again into this land: for I will not leave thee untill I have done that which I have spoken to thee of .

Nor ever after: for so the word until is frequently used, as 2 Sam. 6. 23. Mat. 1. 25. not so as to exclude the time following, but so as to include all the foregoing time, wherein the thing spoken of might be most suspected or feared, as here the worst and most dangerous state in which Iacob was or was like to be was this time of his Banishment from his Country and Kindred, against which he is therefore particularly armed and comforted in these words.
