My sisters refrigerator makes ice. Two kinds of ice, no less. The display panel offers cubed or crushed. I chose cubed. This is what I got. I don’t know if this three-dimensional shape has a name, but if it does, it’s not a cube. Yet this is an ice cube. And I was not at all surprised, disappointed or indignate when I selected “cubed” and got this. I didn’t feel mislead or duped. I’m perfectly happy with my ice cubes that aren’t cubes at all. The ice cube trays (There’s that word again!) of my youth produced ice in the shape of cubes, roughly speaking. I suppose that’s how chunks of ice made for human use came to be called cubes.
How did it happen that we are happy to call something a cube that’s not at all a cube? Well, “ice cube” ceased to be a combination of two words each with its own meaning and instead developed one meaning. We still write it like two words, and we can take it apart into two words, but the two words together have one meaning. We recognize ice cubes that are not even remotely shaped like cubes proving that “cube” has lost its independent meaning when found in the combination “ice cube”. There are lots of such cases, like “the White House”. It’s still white, but it’s quite unlike most houses.
The correctness of considering ice cube as one word is shown by the fact that in other languages it is one word. In German it’s a compound word (like icecube), but in French it is one word (glaçon) that is not composed of two parts. Glaçon is derived from the word for ice but it has nothing to do with cubes.
When translating or interpreting the Bible, we can’t pull phrases like “ice cube” apart to determine their meaning. In fact, we should be a bit sceptical when preachers make a big deal of subjecting words and phrases to great scutiny especially when the result is a novel interpretation. God spoke to us in ordinary language which is subject to ordinary understanding. So don’t think you need deep scrutiny of words to understand. Or you might be like someone convinced by fancy reasoning that my sister’s refrigerator doesn’t make ice cubes. Or that a quarantine is not a real quarantine unless it last 40 days.
