Galatians 3:16

16τῷAndδὲto AbrahamἈβραὰμwere spokenἐρρέθησανtheαἱpromisesἐπαγγελίαιandκαὶto theτῷseedσπέρματιof himαὐτοῦ·Notοὐit does sayλέγει·andΚαὶτοῖςto seedsσπέρμασιν,asὡςofἐπὶmanyπολλῶν,butἀλλ’asὡςofἐφ’Oneἑνός·andΚαὶto theτῷseedσπέρματίof youσου,whoὅςisἐστινChristΧριστός.

Now the promises were spoken to Abraham and to his seed. It does not say “and to seeds,” as of many, but as of One, “and to your seed,” who is Christ.
