Matthew 13:47-ἐκ παντὸς γένους

Greek (WH): Πάλιν ὁμοία ἐστὶν ἡ βασιλεία τῶν οὐρανῶν σαγήνῃ βληθείσῃ εἰς τὴν θάλασσαν καὶ ἐκ παντὸς γένους συναγαγούσῃ·

NIV: “Once again, the kingdom of heaven is like a net that was let down into the lake and caught all kinds of fish."

ESV: “Again, the kingdom of heaven is like a net that was thrown into the sea and gathered fish of every kind."

Jacob J. Scholtz writes:

In contrast with the previous two parables, the parable of the dragnet "is concerned with securing many items (fish) rather than just one item of value" (Bailey 1999b:282). Using a dragnet results in an indiscriminate and mixed catch of all kinds (ἐκ παντὸς γένους) and sizes, edible and inedible,
saleable and useless (Kistemaker 1980:62). The catching of "every kind" (γένος) is more commonly used for a "race" or "tribe" of people: "An allegorical meaning for these details is thereby confirmed; the different kinds of fish stand for different nationalities of human beings" (Blomberg 1990:202).
By God’s might the nations will be gathered before him (cf. Hab 1:14−16; Snodgrass 2008:488).

Blomberg adds:

“All kinds” (v. 47) is, more literally, all races, a strange way of speaking of fish but a natural way of emphasizing the universality of God's judgment of people.31

To Which Mountain Was Jesus Taken?

A student once asked me from which mountain Satan showed Jesus all the kingdoms of the world and their glory (Matthew 4:8-11). We discussed how the mountain is not given a name in the account and it might even have been visionary, but also the word for "mountain" (ὄρος) appears numerous times in Matthew's Gospel (5:1; 5:14). However, these mountains are left nameless most of the time, I believe. For example, in the Sermon on the Mount (chaps. 5-7), we are not told what the mountain is and the same thing can be said for Matt. 17 with the transfiguration. In Matt. 28:16-20, Jesus gives the so-called Great Commission to his disciples from a mountain: Οἱ δὲ ἕνδεκα μαθηταὶ ἐπορεύθησαν εἰς τὴν Γαλιλαίαν εἰς τὸ ὄρος οὗ ἐτάξατο αὐτοῖς ὁ Ἰησοῦς.

There is also the question of how was he taken, and from which mountain one could possibly see all the kingdoms of the world and their splendor?

Matthew 6:22 and the Simple Eye

Commenting on Matthew 6:22, Blomberg writes:

[Note] 76: “ 'Good' is actually the more specific word , [haplous] implying single-minded devotion and/or generosity."

Blomberg, Craig L. Matthew: An Exegetical and Theological Exposition of Holy Scripture (The New American Commentary) (p. 135). B&H Publishing Group. Kindle Edition.

I think the context of Matthew 6:22 also supports this understanding of the text (Mt. 6:24-33).

On the other hand, Zerwick-Grosvenor take haplous in 6:22 to mean "simple, unmixed, clear/clear-sighted" when used of the eye in contrast to an eye that is poneros (possibly unhealthy or not clear-sighted).

From Vincent's Word Studies:

"Single (ἁπλοῦς)

The picture underlying this adjective is that of a piece of cloth or other material, neatly folded once, and without a variety of complicated folds. Hence the idea of simplicity or singleness (compare simplicity from the Latin simplex; semel, once; plicare, to fold). So, in a moral sense, artless, plain, pure. Here sound, as opposed to evil or diseased. Possibly with reference to the double-mindedness and indecision condemned in Matthew 6:24."
