This is one of the many verses which link wisdom and understanding together – this time in parallel Hebrew poetry. Throughout Proverbs these two qualities are associated and used almost synonymously. It’s as if they come together, like bananas in a bunch or grapes in a cluster.
The first line says anyone who loves wisdom actually loves his own soul. Appreciating wisdom in our lives really does good things for us. The second says to cherish (synonymous term with love) understanding will prosper us.
Once we’ve made the commitment for these qualities to become priorities in our lives, they set us up to appreciate and enjoy life better…and to succeed. Jesus said it this way, “I came that they may have life and have it abundantly!” (John 10:10 ESV).
