The Septuagint was a translation of the Old Testament and not the New Testament. Besides that,
1 Corinthians 3:11–15
Matthew 12:32
Revelation 21:27
Hebrews 12:14
1 Peter 1:6–7
2 Timothy 1:16–18
Matthew 5:25–26
Philippians 2:12
Nothing in these verses say anything about praying for the dead. I do not know what bible you are reading from.
1 Corinthians 15:29 speaks of Baptizing for the dead which was a custom in Corinth and was used in an argument for the resurrection. I do not see it practiced anywhere else in scripture.
