Now it happened after the death of Moses the servant of Yahweh, that Yahweh spoke to Joshua the son of Nun, Moses' minister, saying,
"Jehovah spake unto Joshua  ..." We are not told exactly how God spoke to Joshua.   Hebrews 1:1 declares that God of old times spake "in divers portions and in divers manners," meaning "in different portions and various ways."  What is important here is that God did indeed speak to Joshua, gave him his orders for the conquest of Canaan, and commissioned him to lead the Israelites in that conflict, which in the fullest sense, was indeed a "holy war." "The invasion and conquest of Canaan were accomplished by Israel under Joshua's leadership, in response to God's direct command and in His never failing strength."[4]
