I interpret it within its context. It was war. Samson was a warlord and judge risen to power after the Philistines had invaded Israel. How do you interpret the Philistines attacking? How do you interpret Ukrainian soldiers defeating Russian invaders? How do you interpret US soldiers bombing Nazi German towns?
You can see that originally God created a world without sin and death. From Genesis 3 to 6 humans become violent and God condemns violence and even protects Cain the first murderer from being avenged. That didn't work, so after Noah's flood, God sort of accepts that humans are violent but caps their vengefulness with head for head, the death penalty, thus banning intergenerational family feuds at least. Then God narrowed his focus down to one nation, Israel. Of course that meant military and laws to control the population and protect them from other nations were allowed. That failed too, humans failing even to just keep the law of Moses, which, if you study judicial systems back then, it was far more progressive than Babylonian laws for example. Then came Jesus, and ended the era of nationalism and the law, where the kingdom of God is now spiritual, not national. Jerusalem is no longer the capital of worship. Matthew 21:43: "Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof." Luke 17:21: "Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you." John 4:21: "Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father." Jesus came to restore the paradise God created originally, where humans were not supposed to do violence against each other, before Cain (and ultimately in the resurrection and the new earth after the second coming where all sin, pain, sorrow, violence and death will forever be done for all eternity). While waiting for the second coming and resurrection, Christians are not supposed to fight political wars for a physical nation anymore while in this life. We have now churches for community instead of nations, and non-violent pastors for leaders instead of warlords, kings and judges. Old Testament Israel kingdom was a mere footnote in God's plan. Confusion arises when Christians mix Mosaic laws or Old Testament stories with Jesus' commandments about the spiritual kingdom of God which is now (with church communities, and churches are never commanded to perform violence or meddle in politics). It would be like imagine an American expat in China committing a crime but demanding to be judged according to American law. Or an American white man in 2024 demanding his black neighbor be made a slave by the court by citing laws from the 1700s. It would be ridiculous. Paul explained how the Old Testament is there for Christians showing how NOT to be a follower of God. 1 Corinthians 10:11: "Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come." Hebrews 7:22: "By so much was Jesus made a surety of a
better testament." Hebrews 8:6: "But now hath he obtained a more excellent ministry, by how much also he is the mediator of a
better covenant, which was established upon better promises." Jesus said certain things in the mosaic law were only there as permission, not because it was ideal. Mark 10:5: "And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept."
There is no such thing as a Christian nation.
Yes, a tribal war God back then. But since Jesus came, there is no more physical tribe or nation or kingdom with laws to defend. Matthew 21:43: "Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof." That "nation" is spiritual consisting of all believers, not of political institutions. Luke 17:21: "Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is
within you." John 4:21: "Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain,
nor yet at Jerusalem, worship the Father."
