The prophecy concerned a:
1-future Jewish state
2-a monarchy by the tribe of Judah
3-a religious law
4-the coming Messiah
5-the end of the monarch
6-the end of the Jewish nation
7-the Messiah is accepted of the Gentiles
that's seven prophecies in a single verse.
And Jacob was a tribal elder, living in Egypt.
Are you implying as most do that biblical prophesies are evidence of a superhuman knowledge, that is, words that could not have come from unaided human beings? If not, why talk about them?
If so, the claim can be rebutted. Prophecy can be deemed low or high quality. Low quality prophecy is often vague, may be made after the fact, may predict something unremarkable, may contain inaccuracies, or may be self-fulfilling. This describes all biblical prophecy. Consider messianic prophecy. The messiah of Isaiah doesn't resemble Jesus much at all for reasons given in part here already.
And it is self-fulfilling as well. If you're expecting a messiah, it's easy to point a finger at somebody and say, "Him!" Not much prescience needed for that.
High quality prophecy is unambiguous, specific, and detailed - often specifying time and place. It predicts things not commonplace nor expected. It is all accurate, that is, not mixed with errors. The prophecy must precede that which was predicted, but cannot be self-fulfilling.
There was a movie called Frequency some years back in which Dennis Quaid's character’s son contacts his father from his father's future by ham radio. To convince his father that he really is calling him from the father's future - from 1998 back to 1969 - the son discusses the outcome of game five of what is for the father the as-yet unfinished 1969 World Series, which the father is watching live (for him) on TV in a local pub:
"
Well, game five was the big one. It turned in the bottom of the 6th. We were down 3-0. Cleon Jones gets hit on the foot - left a scuffmark on the ball. Clendenon comes up. The count goes to 2 and 2. High fastball. He nailed it. Weis slammed a solo shot in the 7th to tie. Jones and Swoboda scored in the 8th. We won, Pop."
Then the father watches it happen on TV.
That's high quality "prophecy." That's a convincing knowledge of future events, once fraud such as a tape-delayed broadcast of an already played game is ruled out. Extremely specific and unexpected, and accompanied by no error. Biblical prophecy can't compare to that.
But would you like to know what does? Scientific prophecy. Scientific prophecy meets the criteria of high quality prophecy.
Early last century, Einstein predicted that gravity bends light, something that turned out to be correct, but was not known to be true at the time, nor expected. And he provided specifics on how much it would bend. A clever experiment involving distant starlight grazing by the edge of the eclipsed sun on its way to earth demonstrated that the sun caused a deviation in the path of that distant starlight causing the star to appear to be in a position in the sky in which it was known not to be, Einstein also accurately predicted to what degree the curving of the starlight would displace the apparent position of the star, that is, how far from the star's know position its apparent position would be.
The Big Bang theory predicted that because there had been a time in the early universe's past when it cooled enough to allow electrons to join protons and neutrons and form neutral atoms, we should find the ghost remnant of the decoupling of light from matter that then occurred, a faint electromagnetic radiation coming from every direction in space at a fixed intensity and wavelength ought to be present in our universe. Once again, this was unexpected. A few years later, the cosmic microwave background was found, and it was at the precise frequency (temperature) predicted.
The recent find of the Higgs boson at precisely the energy predicted, and with the other characteristics predicted (charge, spin, parity) is the latest triumph in scientific prophecy. So great was the scientific community's and its underwriters' confidence in science and its ability to prophecy, and incredibly large, powerful, and expensive device, the Large Hadron Collider was built to find the particle, which was right where it was predicted to be.
These predictions and the confirmatory findings that followed them are all examples of high quality prophecy. They all outperform biblical prophecy, which is all low quality prophecy as defined above - trivial predictions, vague predictions, etc..
Even so, scientist do not claim to possess superhuman knowledge, and do not offer their prophecies and their confirmations to be evidence of more than quality thinking by human beings, not divine knowledge. If believers are presenting their biblical prophecies as support for a superhuman element in the authorship of those prophecies, they shouldn't expect much success outside of their gatherings with fellow believers.
