'Dependent' in the Bible

Because if the heritage is by the law, it is no longer dependent on the word of God; but God gave it to Abraham by his word.

Now the mediator or go-between [in a transaction] is not [needed] for just one party; whereas God is only one [and was the only One giving the promise to Abraham, but the Law was a contract between two, God and Israel; its validity depended on both].
