What Happens When You Ask What a Word Means

There’s a moment in careful Bible reading that I’ve come to love — and it happens when you find a word that refuses to behave the way you expected.

You’re moving through a familiar passage, reading it slowly for once, and you hit a word that you’ve always assumed meant one thing. And then you stop and ask: does it, though? And you look it up. And it turns out the word is doing something you never noticed.

That moment — the small surprise of a word opening up — is one of the best things biblical literacy can offer. It doesn’t require a seminary degree or a shelf full of commentaries. It requires the willingness to pause at the words that feel transparent and ask whether they really are.

This week we’ve been working through the Lord’s Prayer petition by petition, and one word stopped me in a way I want to share.

The petition is: “Give us this day our daily bread.”

The word that stopped me is “daily.”

In English, “daily” feels entirely clear. Every day. Routine. Regular. We don’t slow down for it. But the Greek word behind it — epiousios (ἐπιούσιος) — is one of the strangest words in the New Testament. It appears exactly twice in the entire New Testament: once in Matthew’s version of this prayer, and once in Luke’s. And outside of these two passages, it appears almost nowhere in ancient Greek literature at all.

Scholars have puzzled over it for centuries. The most widely accepted understanding is that it refers to bread for the coming day — the bread you need for what is immediately ahead. Not a week’s supply. Not abundance. Not more than enough. The bread for today.

Which means this petition is not asking for security. It’s asking for sufficiency. There’s a difference — and the difference matters.

Exodus 16 makes the same distinction. God provides manna in the wilderness, but with a specific structure: gather what you need for the day. Those who gathered extra found it spoiled by morning. The provision was designed to create daily dependence rather than accumulated security. You could not hoard your way to being okay. You had to come back the next day and trust that what you needed would be there.

The Lord’s Prayer asks for bread in exactly that spirit. And suddenly “daily bread” is not a routine petition about routine provision. It is a posture — a daily choice to receive what is given for today rather than anxiously securing everything that might be needed tomorrow.

Jesus says this explicitly a few verses after the prayer ends: “Do not worry about tomorrow, for tomorrow will bring worries of its own. Today’s trouble is enough for today” (Matthew 6:34). The prayer and the teaching are making the same point. We just didn’t notice, because we stopped reading after “amen.”

One word. Epiousios. And the petition it belongs to has more weight in it than we thought.

This is why we slow down. This is what asking what a word means actually does. The text is not waiting for us to already know things. It’s waiting for us to be curious enough to stop and look.

We know every word. But do we really know what we’re saying?
