God doesn't change? Exodus: "thou shalt not murder" Joshua: "Go, and kill every last one of them, including women and children right down to the newborn" (or words to that effect. That isn't a fundamental shift in stated policy?

Joshua was acting explicitly at G-d's command.

Exodus 20:13 says, "Thou shalt not kill [ratsach]". The word "kill" does not occur in the book of Joshua, but the word harag does.

ratsach is ALWAYS used to describe what we in English call "murder".

harag on the other hand is used in the Book of Joshua as an act of G-d's judgment. It is most often translated "slay" or "destroy".

G-d does not change. He is always the same...

[demosthenes the elder]

what a lovely dialectical doughnut you just crafted.
MURDER is a human term, for a human concept.
GOD (it isn't a name, so quit the idiotic modesty, it isn't blasphemy to say or type "God") commanded the Hebrews "Thou shalt not murder." Period. No exceptions either listed or implied. He shortly thereafter ordered Joshua to slaughter noncombatant women and children, including infants and the unborn. That is MURDER.
So, pure and simple, GOD CHANGED HIS TUNE.
