Upon entering the house they saw the child with Mary his (autou | αὐτοῦ | gen sg masc3rd) mother, and falling to their knees they worshiped him (autō | αὐτῷ | dat sg masc3rd). Then opening their (autōn | αὐτῶν | gen pl masc3rd) treasure chests, they presented him (autō | αὐτῷ | dat sg masc3rd) with gifts, gold and frankincense and myrrh.
