In no particular order I’d only make the following comments.

1. the Bible narrative clearly depicts a jealous, wrathful God (YHWH) fully capable of using violence to protect Israel, and also to punish Israel. And sinners, particularly idolators, in general. The message in the OT is clear: God is protective; God will cajole, implore and fully enable His people to succeed in military confrontations. God insists on having complete victories; not mere shallow triumphs. There is NO WAY to escape this part of the narrative because it is so prevalent throughout the OT. God will also lift His protective covering, allowing the enemies of His people to bring Israel into bondage; to destroy their temple; to ransack Jerusalem; to all but destroy the Israelites. But - and this is important - God is FAITHFUL to His Word - His covenant with the Israelites - and never lifts His hand of grace from them. The Israelites simply must REPENT, turn away from their unrighteous, unGodly ways, re-align themselves to a place of worship (obedience) and complete understanding of how faithful and awesome God is, and that is when they prosper. Unfortunately, there are not too many places in the narrative of the OT where this happens. Which is why God sent Jesus…

2. the God of the narrative of the NT is not any different. The narrative is different. Jesus is God in the flesh, conceived and brought to earth to provide the PERFECT way out for a persistently disobedient and unrepentent population of Israelites. And the entire world! The narrative of the NT focuses much more on LOVE and the SPIRITUAL blessings of God. The impartation of the Trinity is a huge quantum leap that distinguishes the NT from the OT in so many ways that the comparisons are really more revelational than relational… and perfect in every way. As many (not here) have pointed out, that is why the Bible really fully defends itself; it is impossible to read the Word with an open consciousness and not be convicted of God’s incredible righteousness and the imperative for us to worship and honor Him. But that’s a rabbit trail I won’t go down just now.

3. The God - principally in and through Jesus and the Holy Spirit - of the NT is in NO WAY posterior to the YHWH of the OT. God never changes… He exists outside of time anyway! The "violence" of the "genocide of the Canaanites" or, for that matter, of the defeated Amalachites, et al. all vanquished - repeatedly - throughout the narrative of the OT is wholly consistent with Jesus and his teachings. Again, the narrative has simply changed. God is still omniscient, omnipotent, always faithful, expecting (and deserving of) all honor and praise, AND most loving and full of grace.

4. The fact that there is a paradigm shift in the narrative of the Bible, or rather, a paradigm shift between the OT narrative and the NT narrative, in no way compromises or alters the legitimacy of the Jesus teachings or the OT teachings. In fact, they are “married” - if you will - in Revelation when there is CLEARLY the mother of all eschatological battles - terrible violence - which will result in the violent decimation of humanity on a scale not seen even in the OT. Again, the tremendous wisdom and the totality of the narrative of the Bible completes itself - is made perfect - and if some want to instead describe this as "tension" sobeit, but I would simply refer to it as "it is what it is." What about the flood? Was that not God in one of His most "violent" decisions about how to punish a fallen, unrighteous, unrepentant and disobedient people? YHWH, in delivering Jesus and the Holy Spirit to us, simply offered us a better - actually a perfect - covenant. And that is the focus of the NT.

5. Jesus clearly focuses His ministry on preaching the Kingdom of God, and on teaching us how the Kingdom has arrived with His manifestation and subsequent resurrection and also with the impartation of the Holy Spirit. But the message in his teachings was clear: violence was not to be the means by which God’s people, under the new covenant, operated. The covenant was primarily of LOVE, and while we are supposed to walk in perfect love and righteousness, we are ASSURED by Jesus himself that violence and oppression and great evil will confront us daily. But we are now personally fully equipped to handle all of these tribulations thanks to God’s awesome NT plan and Jesus’ teachings.

“Texts of terror” might be an uninformed way of interpreting the narratives of the Bible. But in reality the Bible simply tells - in great detail and with great precision and with overwhelming imagery and passion - the story of God’s creation who (or that?), when first confronted by evil, was tempted, fell far from grace, and has been struggling ever since to be restored to the place of righteousness that will only become fully manifest forever when Jesus returns to claim his Bride.
