Luke 24:53 New English Translation

⁵³and were continually in the temple courts^[a] blessing^[b] God.^[c]

Luke 24:53 tn Grk “in the temple.”sn Luke’s gospel story proper ends where it began, in the temple courts (Luke 1:4-22). The conclusion is open-ended, because the story continues in Acts with what happened from Jerusalem onwards, once the promise of the Father (v. 49) came.
Luke 24:53 tc The Western text (D it) has αἰνοῦντες (ainountes, “praising”) here, while the Alexandrian mss (P⁷⁵ א B C* L) have εὐλογοῦντες (eulogountes, “blessing”). Most mss, especially the later Byzantine mss, evidently combine these two readings with αἰνοῦντες καὶ εὐλογοῦντες (A C² W Θ Ψ ƒ^1,13 33 M lat). It is more difficult to decide between the two earlier readings. Internal arguments can go either way, but what seems decisive in this instance are the superior witnesses for εὐλογοῦντες.
Luke 24:53 tc The majority of Greek mss, some of which are significant witnesses (A B C² Θ Ψ ƒ¹³ M lat), add “Amen” to note the Gospel’s end. Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Further, since significant witnesses lack the word (P⁷⁵ א C* D L W 1 33 it co), it is evidently not original.
