Mark 7:10

Μωϋσῆς γὰρ εἶπεν. Mt. makes the connexion more clear and the contrast more pointed by writing ὁ γὰρ θεὸς εἶπεν. The Pentateuch was quoted as “Moses” (Mark 1:44; Mark 10:3; Mark 12:19). But the Law was given διὰ (not ὑπὸ) Μωυσέως (see on John 1:17). Moses was not the giver of it any more than of the manna (John 6:32). See on Mark 12:26.

Ὁ κακολογῶν. He that speaketh evil of (R.V.) rather than “he that curseth” (A.V.); in Mark 9:39, and Acts 19:9, A.V. has “speak evil of,” and in the Corban case there is no cursing, but the parents are dishonoured. These quotations from Exodus 20:12; Exodus 21:17 illustrate the fact that citations which are found in more than one Synoptist, “with few exceptions, adhere closely to the LXX., the differences being only textual or in the way of omission” (Swete, Introd. to O.T. in Greek, p. 393).
