The more verses compared the better picture we will have. The words that appear to be in variance are in red. Remember that the Dead Sea Scrolls have been carbon dated to a time prior to Jesus on earth and should warrant a deference to them. The have refused to carbon date the LXX and therefore the age of the LXX has to be brought into question, especially in light of it's history. There may be some bias in the color coding. I tried not to. These are all translations and the LXX is a double translation. In Genesis 3:13 the Hebrew word for "what" could also be translated why, but they have a different meaning.
The verses were picked at random. A lot of the dead sea scrolls are fragmented so in picking the verses there had to be four consecutive verses of the DSS.
