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" F19, 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.
