More wondering...

in Genesis 6:3, it says that...God says that men are mortal (in the footnotes it says corrupt) so He will limit their days to 100 and 20 years.  That was either yesterday or the day before that's reading.  Today, in Genesis 11:11, it says that Shem lived 500 years and had other sons and daughters.  I asked Solomon and he's like, "Well, Noah's family wasn't corrupt as much as the rest of mankind.  120 years is probably what everyone can expect to live up to, but not necessarily the exact number of years that they will live up to"...is that right? Oh well...

and then, in Genesis 11:1,about the Tower of Babel, when the LORD(i cant do small caps) says "come, let us go down and confuse their language so they will not understand each other." does that refer to the Trinity? and the LORD says that a lot in the Bible in many situations...? 

also, Genesis 11:29 says that Abram's wife is named Sarai.  But i always thought that Abram's wife was named Sarah?? i dunno...

and in Genesis 14:14-16, it talks about Abram rescuing Lot from these kings that allied together...but werent those kings that were allied together like...unstoppable or something? and then Abram goes to rescue Lot and he takes them down with 318 people...the power of God...~^_^~

and finally, in Genesis 14:18-24, it says that Abram gives him a tenth of everything and then the king of Sodom saying like, give me the people and keep the goods to yourself and then Abram saying that he wouldnt accept anything so that the king couldnt say that he made Abram rich...but wasnt it Abram's stuff in the beginning? or maybe i just didnt read the scriptures right...? ;_;
