'Espoused' in the Bible

Oh that I had in the wildernessA lodging place (a mere shelter) for wayfaring men,That I might leave my peopleAnd go away from them!For they are all adulterers [worshiping idols instead of the Lord],[They are] an assembly of treacherous men [of weak character, men without integrity].

“Egypt is a very pretty heifer,But a horsefly (Babylonia) is coming [against her] out of the north!
