Jacques More writes about “election” in relation to the LXX:

In Pharaoh’s dream that Joseph interpreted a contrast between emaciated cows and fat fleshed quality cattle is made. The emphasis that prime and quality beef is in view is given by eklektos.

The best chariots and young men – guys in their physical prime – are seen as the best of their kind by eklektos.

The highest branches, the most desired country, the quality of solid tried stone, the clarity of the sun, with the pure You will show Yourself pure, all are expressed by eklektos.

There is an overwhelming and clear recognition by these that eklektos is about QUALITY.

This is the clear testimony of the Scripture text quoted regularly by Jesus and the apostles.
So that, with “quality” in mind with words like “pure”, “tried”, “fit”, what do you think of Jesus’ following words?

Many are called, but few eklektos.

Matthew 20:16 & 22:14

Is it not better recognised as: “few are fit” or, “few are up to the task”?

This is why I translate this as,

. . . for many are called, but few have mettle.

Matthew 20:16 & 22:14 JM

So, was Jesus selected?
Or, is He Special?
Were angels picked out?
Or, are they “the good ones”?

Answer: The evidence from the LXX points to the latter.
