divisim

In Att[ic Greek], when σὲ αὐτόν, ἐμοὶ αὐτῷ, etc., are read divisim, they are emphatic, not reflexive.

1940, Henry George Liddell and Robert Scott, A Greek–English Lexicon, s.v. “αὐτός”, sense A.I.10.b

In connexion with the person[al] Pron[ouns], “ἐγὼν αὐτός” Od[yssey] 2.194; “σέθεν αὐτοῦ” Il[iad] 23.312; “νωΐτερον αὐτῶν” 15.39 (always divisim in Hom[er])…after Hom[er] in the oblique cases αὐτός coalesces with the Pron[oun], ἐμαυτοῦ, σεαυτοῦ…, ἑαυτοῦ, etc.
