Commentaries:
Robertson's Word Pictures (NT)
No man can serve two masters (oudeiv dunatai dusi kurioiv douleuein). Many try it, but failure awaits them all. Men even try "to be slaves to God and mammon" (Qew douleuein kai mamwnai). Mammon is a Chaldee, Syriac, and Punic word like Plutus for the money-god (or devil). The slave of mammon will obey mammon while pretending to obey God. The United States has had a terrible revelation of the power of the money-god in public life in the Sinclair-Fall-Teapot-Air-Dome-Oil case. When the guide is blind and leads the blind, both fall into the ditch. The man who cannot tell road from ditch sees falsely as Ruskin shows in Modern Painters. He will hold to one (enov anqecetai). The word means to line up face to face (anti) with one man and so against the other.
