מדרש על במדבר 14:38

And the Lord spoke unto Moses and Aaron in the land of Egypt, saying (Exod. 12:1). Is it not a fact that He spoke only to Moses? Why, then, does the Scripture say unto Moses and Aaron? To indicate that just as Moses was included in the revelation, so too was Aaron. Where do we learn that He did not speak to Aaron? From the verse And it came to pass on the day that the Lord spoke unto Moses in the land of Egypt (Exod. 6:28), that is, to Moses and not to Aaron. Similarly in the above verse He spoke to Moses but not to Aaron. Why did He not speak to Aaron? In order (to enhance) Moses’ honor. However, if that were so, would not Aaron’s honor be diminished? No. For they were equals. You find that whenever two things are mentioned together they are of equal importance. On that day the heaven and the earth were finished (Gen. 2:1), and they are equal. Honor thy father and mother (Exod. 20:12), and they are equal. Joshua the son of Nun and Caleb the son of Jephunneh (Num. 14:38), and they were equals. Similarly, Moses and Aaron were equals.

The shares of the spies, Joshua and Caleb inherited. Whence is this deduced? Ula faid: "The passage says (Num. 14, 38) But Joshua, the son of Nun and Caleb, … remained alive. What is meant by remained alive? Shall we take it literally? For this there is another passage (Ib. 26, 65) Save Caleb and Joshua. We must then conclude that the first-cited verse means that they lived with their shares." The murmurers and the congregation of Korah had no share in the land of Israel. Have we not been taught in a Baraitha that the shares of the spies, the murmurers, and the congregation of Korah, Joshua and Caleb inherited? This presents no difficulty. The Tanna of our Baraitha compares the murmerers to the spies, while the other master does not, as we are taught in the following Baraitha (Ib. 27, 3) Our father died in the wilderness, refers to Z'laphchad, but he was not of the company, refers to the spies; of those who gathered themselves, refers to the murmurers; in the company of Korah, literally. Hence one compares the murmurers to the spies and one does not. R. Papa raised the following objection to the above: According to him who compared the murmurers to the spies, then Joshua and Caleb must have taken nearly all Palestine? [for the majority were murmurers]. Whereupon Abaye answered, "They refers to the murmurers of the company of Korah."
