Amos – General
Amos 1:9 - This is about as close to the Bible saying "slavery is wrong" as you'll get. God threatens to destroy Tyrus for, in part, selling slaves to Edom and thereby "remembered not the brotherly covenant."
Amos 2:9 - God brags about killing off an entire race of giants who were as tall as cedars and as strong as oaks.
Amos 3:2 - God explains that he punishes the Israelites because he knows them so well.
Amos 3:6 - All evil comes from God, despite other verses that say he is good.
Amos 3:7 - This says God reveals his plans to his prophets. But what about those times when God lies through his prophets?
Amos 4:1 - The words "kine" and "masters" here in the KJV are translated as "cow" and "husbands," respectively, in several other versions (NRSV, NIV, NJB, among them). That would mean these "cows" are women, who oppress the poor and act like drunkards.
Amos 4:6-9 - God afflicts the Israelites with hunger, drought, thirst, blight, plagues and more. And he wonders why they don't turn to him?
Amos 4:10-11 - God sends the pestilence, kills young men with the sword, makes the "stink of your camps to come up unto your nostrils," and nearly destroys them (ala Sodom & Gomorrah). And yet God still wonders why the Israelites don't turn to him.
Amos 5:14-15 - God says "seek good," but a few chapters ago, elsewhere in the Bible, God is associated with evil.
Amos 5:16-17 - When there is wailing and mourning, you'll know God's been there.
Amos 5:18-20 - Many Christians look forward to the "day of the Lord," but according to these verses, they shouldn't.
Amos 5:21-27 - Despite their praise, God abhors the Israelites. He is obviously hurt because they didn't offer sacrifices and more while they were wandering in the desert (however many centuries ago that was, and besides, who made them wander in the desert in the first place? God!). Because God's feelings are hurt, he's going to let the Babylonians plunder and kidnap his "chosen people."
Amos 5:22 - God says he won't accept animal sacrifices, but elsewhere that is all that was needed.
Amos 6:8-11, 14 - Because Israel is pretty well off, God feels a need to teach everyone a lesson and let the kingdom be smashed.
Amos 7:9-11 - God promises to destroy those who worship other gods, force the Israelites into captivity, and kill the house of Jeroboam with the sword.
Amos 7:17 - After ordered to stop prophesying, Amos gets nasty with the Amaziah the priest, telling him his wife will become a whore, his kids will be killed, and he'll die in a pagan country.
Amos 8:3, 8, 10 - His wrath continues with lots of dead people, trembling lands, mourning and wailing.
Amos 8:14 - God will eliminate anyone who prays to a different god on the day of his wrath.
Amos 9:1 - Amos sees God standing on the altar, again contrary to the many Bible verses that claim that no one has ever seen God.
Amos 9:1-4 - God will kill "the last of them with the sword," and any that try to escape by diving to the bottom of the sea will be bitten, at God's command, by a serpent. God will set his "eyes upon them for evil, not for good."
Amos 9:15 - Despite this promise, the Jews have been continually uprooted and their lives disrupted over the ages. Even today, their land ownership falls into question.
Obadiah – General
Obadiah 1, 8-9, 18 - God spreads rumours, destroys wise men and understanding, and slaughters the house of Esau.
Obadiah 1, 8-9 - Dt.23:7 say, "Thou shall not abhore an Edomite; for he is thy brother." Yet in Obadiah, the destruction of Edom and its people is commanded.
