And after the league made with him he shall work deceitfully: for he shall come up, and shall become strong with a small people. He shall enter peaceably even upon the fattest places of the province; and he shall do that which his fathers have not done, nor his fathers’ fathers; he shall scatter among them the prey, and spoil, and riches: yea, and he shall forecast his devices against the strong holds, even for a time.
And after the league [made] with him he shall work deceitfully: for he shall come up, and shall become strong with a small people. He shall enter peaceably even upon the fattest places of the province; and he shall do [that] which his fathers have not done, nor his fathers’ fathers; he shall scatter among them the prey, and spoil, and riches: [yea], and he shall forecast his devices against the strong holds, even for a time. (Daniel 11:23-24)
And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.

The Hebrew words translated league and covenant are very similar in meaning according to Gesenius’s Lexicon. The word league means to “join in fellowship”. So during the first half of the 70th week of years Antichrist will gain strength.
