Luke 19:30 πώποτε ever yet

saying, “Go into the village ahead of you, and as you enter it, you will find a colt tied there, on which no one has ever sat. Untie it and bring it here.

John 1:18 πώποτε· ever yet;

No one has ever seen God, but the one and only Son, who is Himself God and is at the Father’s side, has made Him known.

Here: "Ever yet", "at any time." It sweeps across all of Israel's history up to this point, including Sinai.

John 5:37 πώποτε at any time

And the Father who sent Me has Himself testified about Me. You have never heard His voice nor seen His form,

Here: 'Ever, at any time'. It is the same word as in 1:18, 'No one has ever seen God.' The echo ties this verse to the Gospel's prologue.

John 6:35 πώποτε. at any time.

Jesus answered, “I am the bread of life. Whoever comes to Me will never hunger, and whoever believes in Me will never thirst.

Here: Elsewhere in the New Testament this word nearly always looks back ('no one has ever seen God', 1:18). Only here does it look forward, adding 'not ever, at any point' to the closing words of the promise.

John 8:33 πώποτε· ever;

“We are Abraham’s descendants,” they answered. “We have never been slaves to anyone. How can You say we will be set free?”

1 John 4:12 πώποτε at any time

No one has ever seen God; but if we love one another, God remains in us, and His love is perfected in us.

Here: Widens the denial to all of history. The same word appears in the near-identical line of John 1:18.
