Technically, the enthalpy H of a system is the internal energy U and the work needed to achieve its pressure b and volume V.

For a system consisting of subsystems, the enthalpy of the entire system is the combined sum of the enthalpies of all of the subsystems.

Heike Onnes coined a word that did not actually exist in Greek. But the ancient Greek word "θάλπο" (THAL-po) ≈ "warm, glowing" did exist and is related to the modern Greek word "θαλυκρός" (tha-lee-KROS) ≈ "hot, glowing".

This word (and related words) do appear in the LXX and the GNT in various forms.

The word "cherish", from the KJV, has a sense of "heat" or "warmth".

When Paul uses the words translated as "cherish" in the following verses, can a sense of "warmth" make sense in what he wrote?

Note the terms involving "nourish" as that is a common theme in the use of the word.

We often associate "cold" flesh with "dead" flesh - figuratively or in reality.

The modern Greek word "τέκνον" (TEH-knon) ≈ "child" from the modern Greek word "τίκτω" (TEE-kto) ≈ "bear" as in the "bearing" of a child.

Mothers are often described as having a "warm" relationship with their children.

Many older folks will feel cold even in an otherwise warm environment.

In David's old age, a young maiden was used to "warm" him where the KJV word is "cherish".

The Greek root word "θερμή" (thehr-MEE) ≈ "heat" is used here, from which we get English words such as "thermal". "thermos", etc., and which may be related to "warm".

The Latin word "calidum" ≈ "warm" from which we get the English word "calorie" is in a unit of heat.

The Latin word "calefaciat" ≈ "keep warm" is in the above verse.

The Latin word "foveo" ≈ "keep warm, nurture, cherish" from which we get the English word "favor" from the Latin word "faveo" ≈ "good will, favor" which is related to "foveo".

A related word is the modern Greek word "θάλψις" (THAL-psees) ≈ "warm up, heat" which comes from "θάλπω" (adding the "s" sound after the "p" sound).

Wycliffe uses the Middle English word "hoot" ≈ "hot" which is related to "heat".

The German word "ausbrüten" ≈ "incubate, hatch" from which the English word "brood" is cognate. Deuteronomy, literally, "second law", has many rules. Here is a verse before the verse that mentions "θάλπη".

Discussion question: Does this rule apply today? Should it apply today?

We are here interested in the following rule.

The word translated "sitting" in the KJV corresponds to the modern Greek word "θάλπη" (THAL-pee) ≈ "heat".

The the Middle English word "dam" ≈ "dame or mother" and usually of animals or, in this case, birds. The modern Greek word "μητέρα" (mee-TEH-ra) ≈ "mother" is related to the English word "mother"

So if a mother is sitting on a nest of eggs, heating them, one is not to take the mother.

Note that the modern Greek word "τέκνων" (TEH-knon) ≈ "young" is the same word as "child" above (hatched or not hatched, born or unborn).

The modern ecological movement and animal rights movement might applaud this rule. In my area, a small road had a special bridge built under it to allow certain turtles to move back and forth to lay and hatch eggs.

The modern Greek word "παιδιά" (peh-thee-A) ≈ "children" and, as used here, refers to both the born chicks and the ones that have not yet hatched.

Discussion question: How does the modern view change when the nest egg is a unborn baby and the mother is the hen "heating" the unborn "egg"?
