'Abomination' in the Bible

Armed forces of his will arise [in Jerusalem] and defile and desecrate the sanctuary, the [spiritual] stronghold, and will do away with the regular sacrifice [that is, the daily burnt offering]; and they will set up [a pagan altar in the sanctuary which is] the abomination of desolation.

From the time that the regular sacrifice [that is, the daily burnt offering] is taken away and the abomination of desolation is set up [ruining the temple for worship of the true God], there will be 1,290 days.
