Answer and Explanation:
The triple parallelism can be found in the lines "who does not walk in step with the wicked or stand in the way that sinners take or sit in the company of mockers," where the author shows a progression on the type of people the righteous , that is, God's chosen ones cannot keep company.
Parallelism is a literary resource that presents sentences located in sequence, which present the same structure and strength within a text.
