# the commands ... the teaching ... the corrections that come by instruction
These three phrases mean basically the same thing, and together they show the various types of lessons a father and a mother teach. (See: [[rc://en/ta/man/translate/figs-parallelism]])
All three of these mean basically the same thing and are repeated to emphasize the fact that the lessons make life better and easier. Alternate translation: "as useful as a lamp ... as helpful as light in the darkness ... as necessary to follow as the way of life" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-parallelism]])
