This saying affirms that honest poverty is better than dishonest wealth.
«Better is a poor man who walks in his integrity»: This line is identical with 19.1a. See there for comments.
«Than a rich man who is perverse in his ways»: This line is a variant of 19.1b. There it is the “fool” who is said to be “perverse in his speech.” For «rich» see 14.20. «Perverse in his ways» means he has a devious or crooked character.
