'Adultery' in the Bible

Plead with your mother, plead-- because she [is] not my wife, and I [am] not her husband. Let her put away her whoring {from before her}, and her adultery from between her breasts.

And Yahweh said to me again, "Go, love a woman {who has a lover} and [is] committing adultery, just like the love of Yahweh [for] the children of Israel, but they [are] turning to other gods and love raisin cakes."

Swearing and lying, murdering and stealing, and adultery break out, and bloodshed follows bloodshed.

On the tops of the mountains they sacrifice, and on the hills they make offerings, under oak, poplar, and terebinth, because their shade is good. Therefore your daughters play the whore, and all your daughters-in-law commit adultery.

{I will not punish your daughters} when they play the whore, or your daughters-in-law when they commit adultery; because they go aside with whores, and they sacrifice with temple prostitutes, a people that does not understand comes to ruin.

All of them commit adultery, like a burning oven whose baker has stopped from stirring the fire, and from kneading [the] dough until it is leavened.
