Render the biblical verse Proverbs 18:21, placed against a serene background. The script should be artistically done with a watercolor effect, using soft textures and subtle gradients to give the impression of a painting. Color palettes can be shades of calming blues and purples creating a visually pleasing and tranquil artwork, blurring out to form abstract forms in the background. The scene should be devoid of specific real personalities to maintain impartiality and focus on the verse itself.
