Otherwise, you could cherry pick Joel 3:10 to prove the Lord is a warmonger.
“Read on to verses 24 and 25. Context is everything in understanding the scriptures.”
24He that saith unto the wicked, Thou are righteous; him shall the people curse, nations shall abhor him: 25But to them that rebuke him shall be delight, and a good blessing shall come upon them.
The sited passages give no indication that rejoicing in the death of an enemy is OK. (Seems more like approval for someone who rebuked Obama for calling homosexuality normal.)
