Deuteronomy 21.23
Septuagint

oti kekathramenoV upo qeou 
paV kremamenoV epi xulou

New Testament - Galatians 3.13

epikataratoV
paV o kremamenoV epi xulou

Septuagint

for every one that is hanged on a tree is cursed of God 

New Testament

Cursed is every one that hangeth on a tree

Masoretic Text

for he that is hanged is accursed of God

Comments:  The NT and the LXX agree. 

The MT does not mention “a tree” at this point, though it does earlier in the same verse.  The NASB translation of the Masoretic agrees with the ASV:  “for he who is hanged is accursed of God.”  RSV:  “for a hanged man is accursed by God.” 

Interestingly, Lamsa, in his translation from the Peshitta, provides this:  “for he who shall revile God shall be crucified.”
