Why should I define that dirty and ugly ARCHAIC word? Don't you know?Define begotten.
To me, it is an absurd word, that entered through the scripturally crude and poor language Greek.
This happened because foreigners wrote scriptures for the natives in a different language.
In Hebrew, it simply means God TOOK Jacob, David, Ephraim and Jesus as sons (figuratively) just as a man loves his sons.
And God TOOK Abraham as a friend. Abraham was not begotten as a friend.
Hope this helped a lot.
