Ephesians 1:13

Ye also trusted. Gentile Christians. Trusted, which is not in the Greek, is unnecessary. The pronoun ye is nominative to were sealed. In whom. Resuming the in whom at the beginning of the verse, and repeated on account of the length of the clause.

Ye were sealed [ε σ φ ρ α γ ι σ θ η τ ε]. See on John 3:33; Revelation 22:10. Sealed with the assurance of the Holy Spirit. Romans 8:16; 2 Corinthians 1:22; 2 Timothy 2:19.

Spirit of promise. Strictly, the promise. Denoting the promise as characteristic of the Holy Spirit : the Spirit which was announced by promise. See Acts 2:16 sqq.; Joel 2:28; Zechariah 12:10; Isaiah 32:15; Isaiah 44:3; John 7:39; Acts 1:4-8; Galatians 3:14.
