What does Proverbs 16:32 mean?

In this verse Solomon commends the person who controls their temper. The ability to defeat others in battle is impressive, but well-developed self-control is an even rarer gift (James 3:2; Psalm 32:8–9). Solomon makes a similar point in Proverbs 14:29, and again compares self-control to warfare in Proverbs 25:28. This is quite a commendation, as military might was extremely important and well respected in Solomon's time. Nevertheless, self-discipline that puts a lid on anger and controls passions, appetites, affections, and temper is a greater advantage than being a renowned soldier.

In 1 Corinthians 9:24–27 Paul writes about the importance of self-discipline. He points out that athletes practice self-discipline to win a temporary earthly token. Paul, however, sought self-discipline to gain rewards that would never be lost.
