(Proverbs 22:2 KJV) The rich and poor meet together: the LORD is the maker of them all.
The KJV gets is right, the NASB has to get it fancy. “Common bond” (6298) means “meet together”. Check the marginal reading in the NASB. So why get fancy? Sometimes we try to get fancy in simple Biblical teaching. This says that we are not to be separated by wealth or lack of it. There are to be common values and moral principles for all. Our cultural gurus mock this and call them “middle class” values. They are not just mocking things that need to be mocked like materialism expressed by a home in the suburbs. They are also mocking things like fidelity, honesty, trust and admission of our sin.
What brings us together? In Solomon’s day it would have been the Law and the temple. For us it is the living Word and the written word.
So? Look past the cut of clothes and the car people drive. Look at the cut of their jib and the source of the wind that drives them.
