And I say unto you. — The pronoun is emphatic, and stands, as in Matthew 5:22; Matthew 5:28; Matthew 5:32, in contrast with what had gone before.
Make to yourselves friends of the mammon of unrighteousness. — On “mammon,” comp. Note on Matthew 6:24. The word was Syriac in its origin, and was found also, as Augustine testifies, in Punic. It was in common use in the Targums or Paraphrases of the Old Testament, in our Lord’s time, for “wealth” or “riches,” and possibly, as stated by Tertullian, whose authority, as a Carthaginian, may be admitted as of some weight, was applied to some Syrian deity who, like the Greek Plutus, was worshipped as wealth personified. If we admit this view, it explains, what otherwise it is not easy to explain, St. Luke’s introduction of the Syriac word instead of its Greek equivalent. “The mammon of unrighteousness,” the genitive having the same force as in Luke 16:8, is the wealth to which that character for the most part attaches, wealth wrongly gained and wrongly spent. And yet “of that mammon” — or better, out of, or with, the mammon — men are to make friends. The right use of wealth in helping the poor, making men happier and better, leading them to repentance and to God, will gain for us friends, perhaps the very persons whom we have helped, perhaps the angels of God who rejoice over one sinner that repenteth, perhaps even Christ and the Father, who will receive us into “everlasting habitations.”
That, when ye fail,... — The better MSS. give “that when it fails,” so the “mammon,” or riches, on which men set their hearts.
Into everlasting habitations. — Literally, everlasting tabernacles. The word seems chosen, in contrast to the “houses” of Luke 16:4, perhaps in contrast to the “booths” of leaves or branches, transitory and withering in a few days, which entered into the ritual of the Feast of Tabernacles (Leviticus 23:40; Nehemiah 8:15), or with the “tents” which were the symbol of the transitory promises of the older Patriarchs (Hebrews 11:9.)
