Then shall he return into his land with great riches; and his heart shall be against the holy covenant; and he shall do exploits, and return to his own land.
Then shall he return into his land with great riches. For the fulfillment of the prophecy, compare 1Ma 1:19-20 , etc.: 'Thus he got the strong cities of Egypt, and he took the spoils thereof. And after that Antiochus had smitten Egypt he returned again in the 143rd year, and went up against Israel and Jerusalem with a great multitude; and entered proudly into the sanctuary, and took away the golden altar, and the candlestick of light, and all the vessels, etc.; and when he had taken all away he went into his own land, having made a great massacre and spoken very proudly.'
And his heart shall be against the holy covenant. On his way back to Syria he attacked Jerusalem, the metropolis of Yahweh's covenant-people, slew 80,000, and sold 40,000 as slaves (2Ma 5:5-14).
And he shall do exploits - he shall effect his purpose. Guided by Menelaus the high priest, he entered the sanctuary with blasphemies, took away the gold and silver vessels, sacrificed swine on the altar, and sprinkled broth of the flesh through the temple. He carried home 1,800 talents out of the temple (2Ma 5:15-21).
