What is the meaning of Galatians 3:17?

* The two F.O.G. Bibles & Commentary below are currently a work in progress.

What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise.

Berean Standard Bible (BSB)

Now I say this. A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect.

World English Bible (WEB)

And{G1161} this{G5124} I say{G3004}{(G5719)}, that the covenant{G1242}, that was confirmed before{G4300}{(G5772)} of{G5259} God{G2316} in{G1519} Christ{G5547}, the law{G3551}, which was{G1096}{(G5756)} four hundred{G5071} and{G2532} thirty{G5144} years{G2094} after{G3326}, cannot{G3756} disannul{G208}{(G5719)}, that{G1519} it should make{G2673} the promise{G1860} of none effect{G2673}{(G5658)}.

Strong's King James

(17) Now, what I'm saying is this, The Torah-Law which came 430 years later doesn't revoke a covenant previously confirmed by יהוה YAHWEH, or to set it aside, the promise-vow.

The F.O.G*

[17] Here's my point: The law, which came 430 years later, cannot invalidate the covenant יהוה previously established, as that would nullify His promise.

The F.O.G Paraphrase

and this I say, A covenant confirmed before by God to Christ, the law, that came four hundred and thirty years after, doth not set aside, to make void the promise,
