When it is my desire, I will chastise them; And the nations will be gathered against them, When they are bound to their two transgressions.
"Their two transgressions ..." There is no agreement whatever among scholars as to what these two transgressions were, although it is quite generally accepted that it was the rejection of the Theocracy in the enthronement of Saul that constitutes one of them.  Some of the sins thought to be the other one are: (1) the establishment of the cult, (2) defection from the house of David, (3) the calves at Dan and Bethel, (4) their falling into idolatry, etc.  However, it does not appear that any of such things were any more identified with the people of Gibeah than with other places of Israel.  But there is one gross, reprobate sin that can be identified with Gibeah, in addition to their lifting up of Saul, and that is the homosexuality which was the total disgrace of the place.  It is nothing short of amazing that none of the scholars whose works we have read picked this up.  But read the account in  Judges 19:13ff, in which a Levite, lodging overnight in Gibeah, was demanded by a roving band of "homos" who addressed the owner of the house thus: "Bring forth the man that came into thy house that we may know him, etc."  The horrible scenes that ensued were Sodom all over again; and there can be no doubt whatever that the vile, heartless, sexual gut-lust of the Gibeahites was a crime that cried out to God for vengeance, no less than the crimes of Sodom.  That particular crime did not appear to have offended Israel at all!  No, they made a racial war out of it and almost exterminated the tribe of Benjamin; but, as the prophet said in  Hosea 10:9, the battle did not overtake the perpetrators of this monstrous evil at all!  Add to this the fact of sexual lust as the principal sin of the Israelites, however dressed up and disguised as worship to their calf-gods (their she-bulls!), and there appears the probable basis for Hosea's return to Gibeah as a long-standing source of Israel's wickedness.  It could not have been merely the adultery, but homosexuality, because the adultery phase of their false worship had already been pinpointed as having had its principal inception at Baal-peor.
