Hosea 8:1

The Lord commanded Hosea to announce coming judgment by telling him to put a trumpet to his lips. The blowing of the shophar announced that an invader was coming (cf. Hosea 5:8). Israel’s enemy would swoop down on the nation as an eagle attacking its prey (cf. Hosea 5:14; Deuteronomy 28:49). The "house of the LORD" refers to the people of Israel, His household. The reason for this judgment was Israel’s transgression (overstepping) of Yahweh’s covenant (the Mosaic Covenant) and the nation’s rebellion against His Law (the Mosaic Law; cf. Hosea 7:13).
