That's the excuse that every so-called Christian who supports war uses.
Old Testament text....
Key word "Old"....
O.T. rules only apply to Jews, not Christians.
What's funny is that most people don't understand why God commanded David to kill the people of Goliath.
Why he told Moses to kill the Phillistines....
These were all children of the Nephillem (Giants), whom were the offspring of the fallen Angels and women.
They were the reason why God flooded the Earth in the first place. Read Genesis, it says that the Nephillem were on Earth before and after the flood. After the flood meaning the Goliath and the Phillistines. These "things" emerged on Earth once more and God took them out before they spread their wickedness all over the world again....
People take this scripture out of it's context only to justify their wicked deeds. It never will, because they don't even understand it in most cases....
Read the book of Enoch. I don't know why Catholics and Protestants don't acknowledge this book. Parts of it was found along with the dead sea scrolls, telling you that it's legit.
The book goes more into detail of why God flooded the Earth, it says that the spirits of the Nephillim are actually Demons and that's how Demons came to be....
