And called his brethren to eat bread. In courteously receiving his kindred, by whom he had been ill-treated, as his guests, Jacob showed his kindness. Moses also intimates that it was by the special favor of God that, after the most dreadful storm which threatened the holy man with destruction, a placid serenity suddenly shone forth. To the same cause is to be assigned what immediately follows, that Laban departed in a friendly manner: for by this method the Lord openly manifested himself as the guardian of his servant, seeing that he wonderfully delivered him as a lost sheep out of the jaws of the wolf. And truly, not only was the fury of Laban appeased; but he put on paternal affection, as if he had been changed into a new man.

Offered sacrifice upon the mount - It is very likely that Laban joined in this solemn religious rite, and that, having offered the blood and fat to God, they feasted upon the sacrifice.

Then Jacob offered sacrifice upon the mount,.... On Mount Gilead, not in a religious way, in which he could not join with Laban, or admit him to it; but in a civil way he "slew a slaughter" (s), or rather made one; that is, as Jarchi explains it, he slew cattle for a feast, as it was usual to make feasts for the several parties concerned in covenant, see Genesis 26:30,
and called his brethren, to eat bread; the, men that came with Laban, and him also, these he invited to his feast, for all sorts of food is called bread:
and they did eat bread, and tarried all night in the mount; this affair between Laban and Jacob had took up the whole day, at evening they feasted together upon the covenant being made, and then tarried all night to take their rest.

And Jacob sware by the fear of his father Isaac - The God whom his father Isaac feared, who had never served other gods, as Abraham and Nahor had done.
