Déjà vu on a couple of texts that were first seen in yesterday's conversation ...

and seen again today, in (1) the second reading:

If you invoke as Father him who judges impartially
according to each one’s works,
conduct yourselves with reverence during the time of your sojourning,
realizing that you were ransomed from your futile conduct,
handed on by your ancestors,
not with perishable things like silver or gold
but with the precious blood of Christ
as of a spotless unblemished lamb.

He was known before the foundation of the world
but revealed in the final time for you,
who through him believe in God
who raised him from the dead and gave him glory,
so that your faith and hope are in God.

Quite powerful. Note the contrast between perishable - and yet precious? - silver and gold and the presumably imperishable and certainly precious blood of Christ.

and in (2) Precepts homework:

Now go, write it on a tablet before them
And inscribe it on a scroll,
That it may serve in the time to come
As a witness forever.

Not exactly a compelling verse in support of the "infallibility" (that is, indefectibility) of Scripture when one considers the specific context of prophecy against Israel for their disobedience.

I mean, there are more generally applicable verses, like the verse that prefaces most English bibles: The grass withers, the flower fades,
but the word of our God will stand forever. (Is. 40:8)

The Jewish Study Bible comments this way on Isaiah 30:8, "Isaiah is commanded to write his prophecy down, so that when it proves correct, God will be on record as having warned the nation against the Egyptian alliance."

God is vindicating himself, justifying himself, absolving himself of Israel's fate. As if he had to.
