Makes a fellah wonder. Does Ark mean the same thing now, and did it 5,000 years ago? Did it have a specific meaning in one part of Genesis opposed to another? Was it written the same way? I the layman see it as (roughly ) meaning Vessel of Life. The Torah is regarded as the word of G-D, no? Noah’s vessel, an Ark, was the protectorate of all life not scoured from the earth. The modern day Ark found in a temple houses the Torah. The original Ark housed the Ten Commandments.
Are these intended to be regarded as the same idea if not physical item?
Re the origins of the English word, let me point out the name used sequentially by several (English/British) Royal Navy vessels, most notably the WWII aircraft carrier: the Ark Royal.
