Core sense — he was, it wasgenerated
He, or it, was. A verb of the class called incomplete, because, with the agent it includes or relates to, it cannot form a complete proposition; that is, it is non-attributive.
The other verbs of this class are ظَلَّ أَضْحَى أَمْسَى أَصْبَحَ صَارَ, مَا دَامَ مَاٱنْفَكَّ مَا فَتِئَ مَابَرِحَ مَا زَالَ بَاتَ and لَيْسَ.
Each of these puts its noun, or subject, in the nominative and its khabar, or predicate, in the accusative.
The ن in يَكُنْ and the like is often elided irregularly.
كَانَ, stripped of any sense of time, is often used as a copula. (See De Sacy's Gr. Ar. 1. 196.)
So too is كَائِنٌ; for هٰذَا زَيْدٌ and هٰذَا كَائِنٌ زَيْدًا mean the same. (Mughnee, under أَنَّ.)
For كَانَ as a complete, that is, attributive, verb, see حَصَلَ, in three places.
For all their deeds.
"For Thou art He that (ever) regardeth us."
And there were those who said,
Because he possesses wealth and (numerous) sons.
