The concept of the "20 word script" for manifestation is not related to any specific words in the Bible. It is a technique where you structure your desires into a sensible mantra of roughly 20 words and repeat it every day to help you focus and tune your energy to attract what you want. The script can be any 20 words that resonate with you and help you manifest your desires. The idea is that consistently using a 20-worded manifestation script will help you bring your focus and vibration on level with what you wish to attract. Therefore, there are no specific 20 words in the Bible for manifestation.
