Genesis 32:9 And Jacob said, O God of my father Abraham, and God of my father Isaac, the LORD which saidst unto me, Return unto thy country, and to thy kindred, and I will deal well with thee: - Free Bible Online

      9-12. Jacob said, O God of my father Abraham--In this great emergency, he had recourse to prayer. This is the first recorded example of prayer in the Bible. It is short, earnest, and bearing directly on the occasion. The appeal is made to God, as standing in a covenant relation to his family, just as we ought to put our hopes of acceptance with God in Christ. It pleads the special promise made to him of a safe return; and after a most humble and affecting confession of unworthiness, it breathes an earnest desire for deliverance from the impending danger. It was the prayer of a kind husband, an affectionate father, a firm believer in the promises.
