Although this verse begins with the genealogy of Noah, Noah’s sons are not mentioned until the next verse. Rather, the focus was placed upon Noah and his character. He was just and perfect.
The Hebrew word for “just” is spelt Tsade, Dalet, and Qof. Now lets look at the ancient alphabet and see the story that the letters give as insight into this word.
Tsade is a picture of a man laying on his side meaning side.
Dalet is a picture of a door.
Qof in the upright position is a picture of the back of a man’s head meaning behind.
Therefore, to be just gives a picture of a man laying in front of a door, not allowing anything that is on the other side to come in.
It was his efforts of keeping the bad on the other side of the door that made him perfect or whole. He was an example to his generation. The end result was that he walked with God.
It often feels unobtainable to be perfect and to walk with God, but we can all hold the door shut on things we know that are wrong. Just as it takes an effort to hold a door closed on someone trying to get in, it takes effort to keep our door closed to unrighteousness. Start by being just.
It was this just man that did not die until Abraham was 58 years old. I believe that Noah had a direct impact on Abraham, but we will save that for another time.
