Illustrate a scene representing the symbolic elements mentioned in the biblical passage Galatians 4:23-26 NASB. The scene should display two contrasting elements, one representing the covenant from Mount Sinai, that symbolizes bondage, shown as a figure born according to flesh and the other representing the covenant from Jerusalem, a symbol of freedom, shown as a figure born through promise. The scene should incorporate a visual representation of Mount Sinai in Arabia and Jerusalem. The style should emulate digital art, with bright colors and clean lines.
