'Word of the Lord' in the Bible

Now after the death of Moses, the servant of the Lord, the word of the Lord came to Joshua, the son of Nun, Moses' helper, saying,

Then it will be when you have seized the city, that you shall set the city on fire. You shall do it according to the word of the Lord. See, I have commanded you.”

According to the word of the LORD they gave him the city which he asked, even Timnathserah in mount Ephraim: and he built the city, and dwelt therein.

And the children of Reuben and the children of Gad and the half tribe of Manasseh returned, and departed from the children of Israel out of Shiloh, which is in the land of Canaan, to go unto the country of Gilead, to the land of their possession, whereof they were possessed, according to the word of the LORD by the hand of Moses.
