Peter meditated on the Psalms and we should too

I wonder how long the Apostle Peter had been meditating on Psalm 34 before he started writing the Epistle of 1 Peter …

"For,

'Whoever would love life
and see good days
must keep their tongue from evil
and their lips from deceitful speech.
They must turn from evil and do good;
they must seek peace and pursue it.
For the eyes of the Lord are on the righteous
and his ears are attentive to their prayer,
but the face of the Lord is against those who do evil.'"
(1 Peter 3v10-12)
