(Pro 5:6 KJV) Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them.
In comparing the KJV with the NASB I was hit by the meaning of “ movable ” (5128) (unstable NASB). People mess with us by changing the ground rules. They do it all the time. We either don’t notice, think we misunderstood, ignore it or try to correct the issue. It can be something as silly as the students I have had who continually change how they want their name pronounced. It can be as serious as a politician doing a 180 after the election. It can be as everyday as a family member that is messing with your mind.
This is one reason we look to the Bible for our foundations. It does not change. Righteousness is defined and does not waver according to the mood of the individual or culture.
So? Again we are to be aware. There is little that can be done with the person who perpetually changes details or memory. We can be confident in right and wrong. Of course that assumes that we want to know.
