1 Petrus 1:2

1:2 according to the foreknowledge of God the Father by being set apart by the Spirit for obedience and for sprinkling ¹  with Jesus Christ’s blood. May grace and peace be yours in full measure! ² 

1 Petrus 3:20

3:20 after they were disobedient long ago ³  when God patiently waited ⁴  in the days of Noah as an ark was being constructed. In the ark ⁵  a few, that is eight souls, were delivered through water.

[1:2]  ¹ sn For obedience and for sprinkling indicates the purpose of their choice or election by God.

[1:2]  ² tn Grk “be multiplied to you.”

[3:20]  ³ tn This reflects a Greek participle, literally “having been disobedient formerly,” that refers to the “spirits” in v. 19. Many translations take this as adjectival describing the spirits (“who had once been disobedient”; cf. NASB, NIV, NKJV, NLT, NRSV, TEV), but the grammatical construction strongly favors an adverbial interpretation describing the time of the preaching, as reflected above.

[3:20]  ⁴ tn Grk “the patience of God waited.”

[3:20]  ⁵ tn Grk “in which,” referring to the ark; the referent (the ark) has been specified in the translation for clarity. Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation.
