There are other notable killings in 1 Samuel that involve God in one way or another. I didn't include them in God's killings since it wasn't entirely clear (to me at least) that God was directly involved. Here are a few posts about these killings.
- Did God help David kill Goliath?
- David bought his first wife with 200 Philistine foreskins
- David joined the Philistines and committed random acts of genocide for them
Let me know if I missed any or if I got some of the numbers wrong.
