'Abominations' in the Bible

Now when these things were completed, the princes came to me, saying, The people of Israel, and the priests and the Levites, have not separated themselves from the peoples of the lands, according to their abominations, even of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites;

which thou hast commanded by thy servants the prophets, saying, The land, unto which ye go to possess it, is an unclean land through the filthiness of the peoples of the lands, through their abominations with which they have filled it from one end to another through their uncleanness.

should we again break thy commandments, and join in affinity with the peoples of these abominations? wouldest thou not be angry with us till thou hadst consumed us, so that there should be no remnant nor any to escape?
