'Apostasy' in the Bible

Behold, these women {caused} the {Israelites}, by the word of Balaam, to be in apostasy against Yahweh in the matter of Peor, so that the plague was among the community of Yahweh.

Why has this people, Jerusalem, turned away [in] enduring apostasy? They have kept hold of deceit, they have refused to return.

And they will not defile themselves again with their idols and with vile idols and with all of their transgressions, and I will save them from all of their apostasy {by which they sinned}, and I will cleanse them and they will be for me as a people and I, I will be for them as God.
