"In love a throne will be established; in faithfulness a man will sit on it-- one from the house of David-- one who in judging seeks justice and speeds the cause of righteousness."
Isaiah 16:5
"... the angel said to her, 'Do not be afraid, Mary, you have found favor with God. You will be with child and give birth to a son, and you are to give him the name Jesus [Immanuel, which means God with us]. He will be great and will be called the Son of the Most High. The Lord God will give him the throne of his father David, and he will reign over the house of Jacob forever; his kingdom will never end.'"
Luke 1:30-33
