II Ki 15 doesn’t tell us any of the background to Shallum’s deeds. That they are recorded doesn’t necessarily imply that they are approved of. They are just stated.
The text of the Bible is given as a training aid to oral recitation. In parallel with it was a body of doctrine for which the epic was a series of bullet points, cameos, aides-memoires. The doctrine is hung round those. Christian doctrine is regarded as the fulfilment of those and was recognised as such by Jesus and Paul amongst others. See my post from 12.41 today my time about meanings of the seven nations.
In the next few days I’m going to see if I can find detail on the meaning of the Amalekites and the other people mentioned.
It actually was a rough world then.
Attributing what went on in society to God’s desire and planning was a chic way of writing. I think it was a way of getting back through propaganda at people like Assyrians who would boast that because of Assur they did terrible things to all and sundry (except not so much under Esarhaddon, for a period after Jonah had preached).
In addition to which, whatever the degree of what we might call “accuracy” or v.v., the attached teaching was the more important thing to the people telling it.
As another example, one of the flood narratives occupies most of Gen 1 but serves to be attached to doctrine about creation as verse 1 and all of ch 2 are. Indeed it has land reappearing.
Quite frankly some of the detailed meanings of both Testaments are barely known. They are maybe in some book that we aren’t put in touch with.
A very big theme is to not stunt the growth of the widows and orphans, that is people in need of strengthening of heart so they can play their part in strengthening others in turn. The last 21 verses of Proverbs depict God’s profitable family firm. The parable of the talents is about these things too. The meanings of parables and OT passages intertwine.
The nature of the inspiration of Holy Scripture is different from that of the Qur’an as the former are not dictated.
Proof is existential though not many Catholics will tell you that. It worked for the Apostles under pressure, otherwise they’d not have gone along with it. It’s scarcely known what the power of the Paraclete is.
Conversion of heart is the fruit of the indwelling Jesus, or something like that (I’m rather a vague theologian).
Marginal references and a good dictionary like Leon-Dufour show how densely interwoven the Bible is. The marginal references are like hyperlinks.
The nation of the Israelites represents an individual Christian soul and the “seven nations of giants” (in my other post) seven bad attitudes. These can be diminished by application yet with help - like power steering.
