Matthew Poole and continuators on Hosea 5:8

8 Blow ye the cornet in Gibeah , and the trumpet in Ramah : cry aloud at Beth-aven : after thee , O Benjamin.

Ye watchmen, or who ever have the care and custody of these Fortified Towns, sound the alarm, for the enemy cometh.

a Town of Benjamin scituate on a Hill, built by Asa, 1 Kings 15.22. made by him a frontier, and likely alwayes Garrison'd against the incursion of the ten Tribes.

Add to the sound of the Cornet, the Trumpet also, which is proper for war, and will be best understood by the people, lest they mistake the meaning of the Cornet, which is say some a Pastoral Instrument, proper for Shepherds, sound the Trumpet.

Of which there were three, one in Naphthall, and Rama Sophim, and this of Benjamin near Gibeah, and was an inlet into Iudah, of great importance, as appears 1 Kings 15.17, 21. a Town of strength, built on a high hill, and fit to be as a watch Tower. Be you upon your guard when the invader is so near.

As more concerned, cry out with more vehemency, awaken all to prepare for defence, or howl and lament for the things that are come upon thee, O Beth-aven. The Assyrians march will alarm thy Neighbours, but their success against thee will ruin thee utterly, let thine inhabitants therefore cry and howl; Beth-aven, if that scituate in the Wilderness; this passage foretels the destruction of it by the Assyrians, probably in the beginning of their invasion, if 'twere Bethel, 'twas the chief seat of Idolatry, and first or chief in miseries.

Thee, refer'd to Beth-aven speaks thus, after thy cryes, when thou hast howled, let Benjamin and Iudah too begin theirs, for they shall also fall for their sin.
