Isaiah 3 and Leviticus match on the following themes:
Leviticus for the most part is a book of laws directed primarily to the Levites and Priests. There are a few chapters of storyline, however, around the ordination of Aaron and his four sons, in Leviticus chapters 8-10.
Isaiah 3:6 portrays a man grabbing his brother and making him ruler because he has a robe. Curiously, the thing that is placed on Aaron and his sons for their priestly ordination are robes.
Moses is Aaron's brother, so when Moses brings Aaron before the nation and makes Aaron the leader and dresses him in the preistly robe he's acting out Isaiah 3:6. Whatever else Isaiah 3:6 may be the robe identifies the verse as relating to the priest.
The ordination was an eight day process. Day 1 the robes were placed on Aaron and his sons. Then they spent 7 days at the Tabernacle. On Day 8 there was a burnt offering to finish the ordination process. At the burnt offering service two of Aaron's sons offered "unathorized fire" to Yahvah and were consumed in fire as a result.
Isaiah 3:11 references these "wicked" sons.
Aaron's wicked sons reaped what their actions deserved.
Aaron's other two sons were not consumed in the fire, because they were righteous (righteousness is doing what Yahvah asks). They offered sacrifices on the altar just as they were told and the result is they were able to continue as priests and eat the sacrifices.
Isaiah 3:10 addressed the "righteous."
Note the word "tell" that begins this verse. Tell the righteous it will be well with them. Well compared to what? Well compared to the wicked sons of Aaron that were just consumed in the fire. In fact this is precisely what happens in the story in Leviticus. Immediately after the wicked sons die, Moses tells Aaron that he and his remaining sons are to eat the sacrifices they offered.
Just as Aaron's wicked sons reaped what their actions deserved, Aaron's righteous sons reaped what their actions deserved. They were able to eat the "fruit of their hands" as Isaiah says when Moses gave them the sacrifices to eat.
