Albert Barnes Commentary Isaiah 5:9

"In mine ears [saith] Jehovah of hosts, Of a truth many houses shall be desolate, even great and fair, without inhabitant." — Isaiah 5:9 (ASV)

In mine ears - This probably refers to the prophet. As if he had said, ‘God has revealed it to me,’ or ‘God has said in my ears,’ that is, to me. The Septuagint reads it, ‘These things are heard in the ears of the Lord of hosts,’ that is, the wishes of the man of avarice. The Chaldee, ‘The prophet said, In my ears I have heard; a decree has gone from the Lord of hosts,’ etc.

Many houses shall be desolate - Referring to the calamities that should come upon the nation for its crimes.
