Where did the LORD command Moses to destroy the Canaanites without mercy?

Joshua 11:20 (ESV)

20 For it was the LORD’s doing to harden their hearts that they should come against Israel in battle, in order that they should be devoted to destruction and should receive no mercy but be destroyed, just as the LORD commanded Moses.

In Deuteronomy 7:1–5 as well as Deuteronomy 20:16–18, the Lord commanded Moses that the Israelites must completely and totally destroy all the inhabitants of the land of Canaan. They were not allowed to show any mercy to these people.
