All scripture is profitable to us. All scripture is God breathed. But some of it is a warning. Here there are two: do what Christ requires and not what you think will help him, and secondly, do not despise those who God uses because you think you have more virtue points.
Pride is lethal.
12 While he was in one of the cities, there came a man full of leprosy.[a] And when he saw Jesus, he fell on his face and begged him, “Lord, if you will, you can make me clean.” 13 And Jesus[b] stretched out his hand and touched him, saying, “I will; be clean.” And immediately the leprosy left him. 14 And he charged him to tell no one, but “go and show yourself to the priest, and make an offering for your cleansing, as Moses commanded, for a proof to them.” 15 But now even more the report about him went abroad, and great crowds gathered to hear him and to be healed of their infirmities. 16 But he would withdraw to desolate places and pray.
12 Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married, for he had married a Cushite woman. 2 And they said, “Has the Lord indeed spoken only through Moses? Has he not spoken through us also?” And the Lord heard it. 3 Now the man Moses was very meek, more than all people who were on the face of the earth. 4 And suddenly the Lord said to Moses and to Aaron and Miriam, “Come out, you three, to the tent of meeting.” And the three of them came out. 5 And the Lord came down in a pillar of cloud and stood at the entrance of the tent and called Aaron and Miriam, and they both came forward. 6 And he said, “Hear my words: If there is a prophet among you, I the Lord make myself known to him in a vision; I speak with him in a dream. 7 Not so with my servant Moses. He is faithful in all my house. 8 With him I speak mouth to mouth, clearly, and not in riddles, and he beholds the form of the Lord. Why then were you not afraid to speak against my servant Moses?” 9 And the anger of the Lord was kindled against them, and he departed.
10 When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned towards Miriam, and behold, she was leprous. 11 And Aaron said to Moses, “Oh, my lord, do not punish us because we have done foolishly and have sinned. 12 Let her not be as one dead, whose flesh is half eaten away when he comes out of his mother's womb.” 13 And Moses cried to the Lord, “O God, please heal her—please.” 14 But the Lord said to Moses, “If her father had but spat in her face, should she not be shamed for seven days? Let her be shut outside the camp for seven days, and after that she may be brought in again.” 15 So Miriam was shut outside the camp for seven days, and the people did not set out on the march till Miriam was brought in again.
