Ralph, with passages like these it often helps to check other translations. Unless you’re good at going into the original languages, then do that.
I checked Proverbs 16:31 in the NJKV and it’s helpful. “The silver haired head is a crown of glory if it’s found in the way of righteousness”. The phrase Old Age has negative connotations, but Silver Haired Head does not. In either translation I know what it means. Basically, God is saying that if you lived a mostly righteous life, then glory or dignity will be yours in your latter years. This is true. Suppose you lived a life of crime, going in and out of jail, having no real friends, and probably many regrets, unless you have no conscience at all. This person will likely be miserable in old age. This isn’t always true, but it usually is. Read Ecclesiastes to get a good view on how unfair life often is. But in general I’d say this proverb is a truism.
The next one I’m not sure of because I forget what casting Lots meant in ancient times. But they seem to be bad things. So only God can free you of them.
I hope this helped.
