Genesis 28:15 Meaning and Commentary

Genesis 28:15

And, behold, I [am] with thee
Though alone, at a distance from his father's house, no friend to keep him company, or servant to attend him; but the presence of God here promised is abundantly more than an equivalent for all this: and will keep thee in all [places], whither thou goest;
from beasts of prey, in lonesome places through which he might travel; from thieves and robbers, to whom he might be exposed; from his brother Esau, and all his ill designs against him; and from being always under the bondage of Laban, into which he would be brought: and will bring thee again into this land:
the land of Canaan, which was entailed on him and his seed for an inheritance; but, as he would now soon be out of it, and continue in another land for many years, as he did, which would make it look very unpromising that he and his seed should inherit it, this is said unto him: for I will not leave thee, until I have done [that] which I have
spoken to thee of;
made good all his promises to him: and the sense is, not that he would then leave him when he had done so, but as not before, so never after; for God never does, nor never will, utterly forsake his people.

14 And thy seed shall be as the sand of the earth; and it shall spread abroad to the sea, and the south, and the north, and to the east; and in thee and in thy seed shall all the tribes of the earth be blessed.
15 And behold I am with thee to preserve thee continually in all the way wherein thou shalt go; and I will bring thee back to this land; for I will not desert thee, until I have done all that I have said to thee.
16 And Jacob awaked out of his sleep, and said, The Lord is in this place, and I knew it not.
17 And he was afraid, and said, How fearful is this place! this is none other than the house of God, and this is the gate of heaven.
