All this assumes, of course that man is in control of the language. Car is not a biblical word...it is a modern word chosen by man. If God can control micro-organisms and a day can be lived in for a year or more....time being inconsequential to God....then why not the hiding of meanings within words? Why not be more efficient in the use of the very element that frames the universe?
God does not use word plays ALL THE TIME..but they are there. God does not build up words from pictures ALL THE TIME...but there are many that are built this way. Only men in their futile ways are looking for a rigid formula. This may be coming from the idea that a cracker jacks box ALWAYS has a prize in it. But in nature, does every oyster have a pearl???
We have to stop judging God from a consumer perspective. Dr. Pepper may know something about soft drinks...but he is no surgeon. So it is with man's reasonings when it comes to the way God chooses to relay His message to men.
I am not Judging God! Nor do I have a rigid understanding on puns or word play in the Hebrew Text, nor in any language for that matter. I admit, there are lots of word play in the Hebrew Text, non of which involve the methods of this modern pseudo-science. This is my pet peeve. As you admit, and readily, that this method does not work for every word, nor for all cases; which means it is left to the reader, and now the new age interpretor, to supply which words are puns, and full of hidden meaning. This is a misleading interpretive method, and is very deceptive, as it is based upon a lie to begin with, Hebrew NEVER worked in this method, nor was it ever written in this way.
