Galatians 1:20

I assure you before God that what I am writing to you is no lie.

Now the things which I write unto you, behold, before God, I lie not.

Now about the things which I write to you, behold, before God, I’m not lying.

Note “Behold”, from “ἰδοὺ”, means look at, take notice, observe, see, or gaze at. It is often used as an interjection.

Now touching the things which I write unto you, behold, before God, I lie not.
