Where Did the Mission of the 12 Spies Begin?

Did the mission of the twelve spies start from Paran (Numbers 13:3) or from Kadesh Barnea (Numbers 20:1)?

Both statements are true. The Wilderness of Paran extends from the port of Eloth (Eilat) on the Gulf of Aqabah in a north-northeast direction across the the Nahal Paran and Har Ramon to include the site of Kadesh Barnea, which lies on the same latitude as Punon. The spies therefore set out from Kadesh, which is located in the Wilderness of Paran (Numbers 13:26: “in the Wilderness of Paran, at Kadesh").
