The ancient Greek word "ἐκβάλλω" ≈ "throw or cast out" and comes from two Greek words.

• The ancient Greek prefix "εκ" ≈ "out of" such is in "Exodus" (the way out of).
• The ancient Greek word "βάλλω" ≈ "throw, cast, hurl" and is the source of the English word "ballistic".

The Latin word "eiciam" ≈ "eject" and is the source of the English word "eject".

The English phrase "catch and release" is from the activity of fishing whereby one might do the following.

• Catch the fish.
• If the fish is of sufficient size, keep the fish. If not, release the fish back into the water.

Verses where the English only emphasizes one of the two parts of the process act as a red flag of verses which might more analysis in their original Greek form.

In the United States, the phrase has been used for certain immigration and/or police policies of catching or detaining possible illegal immigrants or suspects for a crime and then releasing them back into the population. This is noted here but is not relevant to the current discussion.

If I "throw out" some ideas, do I want an opinion on them or are they destined for the trash? This is where context is critical in understanding what is being said. The same is true for Bible verses using such words. Look and study the context.

Ideas are in the mind. A common English phrase is the "throw out" and idea. To do this, one must first "grab hold" of that idea in the mind in some way.

Note that some people (e.g., marketing types) tend to say whatever pops into their head, so the process of grabbing hold of an idea is very short in duration. On the other hand, engineering types tend to think in a more deliberate manner before throwing out ideas in their head.

In the GNT, notice how many times "cast out" refers to demons. The casting out of demons apparently has two parts. Jesus can do and has, at times, delegated such authority to his disciples.

• Catch or take hold of them in same way.
• Release or throw them out to some target area, such as the swine.

This might be contrasted with the C. S. Lewis idea of a grumbler becoming a grumble.

Here in John, the "out" is emphasized. Sometimes the "outside" is emphasized (or reemphasized) by adding the ancient Greek word "έξω" ≈ "outside" which appears to indicate that not only is it taken and put out but it is put outside of some other boundary - such as a room, etc.

Here is a similar emphasis in Matthew in the seventh (last) kingdom parable.

Note that the "bad" here has a meaning of "rotten" and would, in many cases, not be discernible from outward appearances.

Details are left as a future topic.

The Greek word for "cast out" is a synonym (and also passive) of the word for "fall out" which is the word translated as "faileth" in the KJV (King James Version) in 1 Corinthians 13:8

• The ancient Greek word "εκπίπτω" ≈ "fall out, be thrown out".
• The ancient Greek word "πίπτω" ≈ "fall" or to throw oneself down.
• The modern Greek word "εκπίπτω" (ehk-PEE-pto) ≈ "discount, lose, fall out".

The impetus to have 1 Corinthians 13:8 say "Love never faileth" rather than "Love never falls" or "Love never falls out" is so strong that it appears that this verse is the only place in the GNT where the word is translated this way. Why might this be?

The Latin word "excido" ≈ "fall out" from the Latin word "ex" ≈ "out of" and the Latin word "cado" ≈ "fall" which is the source of the English word "cadaver" from the Latin word "cadaver" ≈ "cadaver".

The Latin word "exicdo" ≈ "fall out" is the source of the English word "excise".
