מִכְלָל

From the study of Psalm 50:2

Range of meaning

'Completeness, perfection'. It occurs only here. It belongs to the root k-l-l, 'to complete, make whole', which also gives kālîl ('entire, perfect', and as a sacrifice term the 'whole' burnt offering), kelîlâ in the phrase kelîlat yōphî 'perfect in beauty', and mikhlôl ('splendid, in full array', Ezek 23:12; 38:4).

Against the English

KJV/ESV/WEB/YLT 'the perfection of beauty' keep the noun and its role as a title. BSB/NIV 'perfect in beauty' turn it into a description, which reads smoothly but is less clearly a fixed title for Zion.

How it drifted

'Perfection' in English can suggest moral flawlessness or something abstract and ideal. The Hebrew means complete, lacking nothing. It is the beauty of something finished and fully adorned, like a city in full splendour. It is not a claim of sinlessness.

Used elsewhere in the period

Lam 2:15 shows the phrase was a known title for Jerusalem: mourners mock, 'Is this the city they called the perfection of beauty (kelîlat yōphî), the joy of all the earth?' That line combines this verse with Ps 48:2 ('beautiful in elevation, the joy of all the earth, Mount Zion'). Ezekiel uses the same language for Tyre ('perfect in beauty', Ezek 27:3–4; 28:12) and for Jerusalem's beauty 'made perfect through my splendour' (Ezek 16:14).
