If we add 60 years to it, Isaac would have been 190 year old (he died at 180) Give an estimate of 10 years (7 years of abundance and 3 years of famine before Jacobs food ran out) We know that Joseph was made the prime minister at the age of 30, and he was sold off to Egypt at the age of 17.
What is ORAL CONTRACT? A contract agreed verbally, but not in writing, the existence of which can be difficult to prove as a result. If an oral contract can be proven to exist, it may void a written contract and vice versa.
Legal, Maybe Not Provable. Entering into an oral contract is one thing, but proving that the contract exists, or that specific terms of the contract exist, is entirely different. Oral contracts are legally dangerous, because there is no concrete record of their existence.
