Jesse was the son of Obed. We know that he kept sheep. He had at least eight sons, seven of which were rejected by God to serve as King. Though David who he left behind would attract the attention of God. Jesse would be surprised when Samuel, a prophet, would have God choose him as Kind. Samuel would anoint David, however he would remain until ready. Jesse would tend to his sheep until he passed away. He played a minor role but in the grand scheme of things his role is invaluable.
