Albert Barnes Commentary Jeremiah 23:11

"for both prophet and priest are profane; yea, in my house have I found their wickedness, saith Jehovah." — Jeremiah 23:11 (ASV)

For both prophet and priest are profane: While by their office they are consecrated to God, they have made themselves common and unholy by their sins. See the note on Jeremiah 3:9.

Yea, in my house: This may refer to sins such as those of the sons of Eli (1 Samuel 2:22), or that they had defiled the temple by idolatrous rites.
