Israel's would sorrow greatly because of her sins. Description of her sorrow precedes the explanation for it.
9:1-2 The Lord told Israel not to rejoice like other nations at the prospect of an abundant harvest; that would not be her experience. He promised to remove her grain and wine. These were threatened curses for covenant unfaithfulness (cf. Deut. 28:30, 38-42, 51). Her unfaithfulness to Him had precluded further blessing. She had credited Baal with providing the blessings that she enjoyed rather than Yahweh. The prophet envisioned Israel as a harlot committing adultery on a threshing floor by worshipping idols there. Threshing floors and wine presses were common places where ritual prostitution took place. It was through these rites that the worshippers sought to stimulate the gods to engage in sex and so bestow fruitfulness on them and their land.
9:3 Israel would not remain in the Promised Land but would go into captivity (cf. Deut. 11:8-21). Assyria, likened here to Egypt (cf. 7:16; 8:13; 11:5), would be the place the Israelites would eat unclean food (i.e., no longer be independent; 2 Kings 17:6; Ezek. 4:13; Amos 7:17). She would eat defiled food in a defiled land because she had defiled herself with sin.
"The place of their captivity was first called Egypt' (cf. 8:13) in order to show its general character; then Assyria was named as the actual place the people would be taken to (cf. 11:5)."62
9:4 Opportunities for legitimate worship would end in exile since Israel had corrupted legitimate worship in the land. Drink offerings of wine, which accompanied certain sacrifices, would cease (cf. Num. 15:1-12), and sacrifices offered there would be unacceptable to Yahweh. They would be similar to the bread that mourners ate, namely, ceremonially unclean because of contact with dead bodies (cf. Num. 19:14-15, 22). Such bread might be suitable for human consumption, but it was unacceptable as an offering to God. Cultic celebration would give way to disease and death.
9:5 Consequently the Israelites would have nothing to offer the Lord when their annual feasts rolled around. These feasts centered around offerings to the Lord, but those offerings would be unacceptable in exile.
9:6 The Israelites would leave their land because of the destruction Yahweh would send. Egypt and Memphis, as two undertakers, would bury the exiles. Memphis (near modern Cairo) was an Egyptian city famous as a burial site because of the pyramid tombs there. Back in the land weeds would overgrow the Israelites' abandoned treasures, and thorns would take over their houses.
9:7 Israel was to know that the days of her punishment and retribution were imminent because the nation's iniquity was fat and its hostility to the Lord was great. Another reason for her judgment was that the Israelites had regarded the prophets whom the Lord had sent to them as demented fools (cf. 2 Kings 9:11; Jer. 29:26-27). This probably included Hosea.
9:8 Ephraim tried to function as a prophet of God warning others of approaching danger. But Ephraim had tried to snare the prophets God had sent the people like a hunter catches birds in a net. Thus there was nothing but hostility in the land of Israel between the Ephraimites and the true prophets of Yahweh. Ephraim saw nothing as a prophet and criticized the prophets for preaching what they saw, namely, coming judgment.
9:9 The Israelites had delved deep into depravity, as when the men of Gibeah raped and murdered the visiting Levite's concubine (Judg. 19). This was another occasion in which the Israelites punished one of their own rather than protecting her. The Lord would remember their iniquities and punish their sins. This sin had resulted in war in Israel and almost the obliteration of the tribe of Benjamin (Judg. 20). War would come again, and God would almost entirely obliterate all the Israelites for their sins.
