Envision an artistic interpretation of Exodus 13:2 - 'Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, both of man and of beast: it is mine.' The scene should be presented in the form of digital art. It should depict ethereal and luminous firstborn humans and animals from various descents among the imagined Children of Israel, each exuding a sense of sanctity and significance. Use a harmonious blend of vivid colors and fluid forms to evoke a sense of spirituality and reverence.
