Hebrews 1:6

New English Translation

⁶But when he again brings^[a] his firstborn into the world, he says, “Let all the angels of God worship him!”^[b]

Hebrews 1:6 tn Or “And again when he brings.” The translation adopted in the text looks forward to Christ’s second coming to earth. Some take “again” to introduce the quotation (as in 1:5) and understand this as Christ’s first coming, but this view does not fit well with Heb 2:7. Others understand it as his exaltation/ascension to heaven, but this takes the phrase “into the world” in an unlikely way.
Hebrews 1:6 sn A quotation combining themes from Deut 32:43 and Ps 97:7.
