Parallelism, which belongs to the literary devices and techniques used by figurative language to make speech more effective, persuasive, and impactful, is the use of components in a sentence that are grammatically the same in their sound, meaning, or meter. It can be identified several types of Parallelism, such as caesura, synthetic, cinquain, synonymous, and contrasting.
In the particular case of the example provided "Thy word is a lamp unto my feet, and a light unto my path” it is possible to see an example of Synthetic Parallelism since the second line not only reinforces the thought of the first one but actually adds to its meaning content.
