set
שת
'set' means “stray”.
Seth
Also known as “Seth”, 'set' was the third son of Adam and Eve, and the ancestor of Noah. See Seth#Family_tree His birth is mentioned in Genesis 4:25. The following verse refers to a fascinating topic which is examined further at The Studies of Seth
According to legend, Seth passed technological knowledge on to Noah for preservation. This narrative is not found within the canonical texts however.
The meaning of Seth's name is very clear. 'set' literally means “stray”. This seems to correlate with his rather unorthodox study.
Wood
'set' is sometimes misunderstood as “acacia wood” but contextually “stray” wood tends to make more sense, given that the Acacia is native only to Africa, Australia, and South America, but not to the middle east. The idea of “stray wood” may apply to scant supplies of dead dried wood found in the wilderness or to salvaged and repurposed wood from earlier ruins.
there is some contextual evidence for the use of 'set', seti, or setim to indicate the numeric value “2”.
