Jewish law allowed God’s people to eat kosher fish with scales and fins: salmon, bass, tuna. But not fish without scales and fins: catfish, sturgeon, dolphin. And no tasty shellfish: lobster, shrimp crab, oyster, clam. See Leviticus 11. Understanding Jesus, p. 172.
The unforgivable sin. Bible experts don’t agree on what it is. But most agree on this much: If you’re worried that you’ve committed it and there’s no way you can get forgiven, you didn’t commit it. “If we confess our sins to God, he can always be trusted to forgive us and take our sins away,” (1 John 1:9 CEV). Bible Snapshots, p. 213.
