No, "Thou shalt not murder." Look up the Hebrew. If God meant "thou shalt not kill even if it is not murder," then He would have been commanding His people to break the Decalogue with every single person they were to kill when they entered the Promised Land."Thou shalt not kill"
And David praised God for his ability to kill in battle: "Blessed be the LORD my strength, which teacheth my hands to war, and my fingers to fight" (Ps. 144:1).
