Ephesians 4:30

4:30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.

Ephesians 1:13

1:13 And when ¹  you heard the word of truth (the gospel of your salvation) – when you believed in Christ ²  – you were marked with the seal ³  of the promised Holy Spirit, ⁴ 

[1:13]  ¹ tn Grk “in whom you also, when…” (continuing the sentence from v. 12).

[1:13]  ² tn Grk “in whom also having believed.” The relative pronoun “whom” has been replaced in the translation with its antecedent (“Christ”) to improve the clarity.

[1:13]  ³ tn Or “you were sealed.”

[1:13]  ⁴ tn Grk “the Holy Spirit of promise.” Here ἐπαγγελίας (epangelias, “of promise”) has been translated as an attributive genitive.
