'Lover' in the Bible

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."

I found Israel as grapes in the wilderness; as first-ripe fruit on the fig-tree, I saw your fathers at the beginning: they went to Baal-Peor, and separated themselves unto that shame, and became abominations like their lover.
