God burned Sodom and Gommorrah with fire and brimstone, killing all but one family in the cities. This was an act of God. Moses led his people from slavery. This was an act of God. The Israelites settled in the promised land, defeating the Cannanites in war to do so. This was an act of God. You don’t understand my argument because you do not apply the premise of a sovereign God. So my syllogism is:
Obedience to God is good.
God commanded the Israelites to kill the Cannanites.
Therefore killing the Cannanites was good.
Your syllogism is:
Killing is bad.
The Israelites killed the Cannanites.
Therefore the Israelites were bad.
Your syllogism leaves out WHY the Israelites killed the Cannanites which is the whole matter of whether it was right or wrong.
"Therefore killing [her children] was good."
