Charles Ellicott Commentary Isaiah 29:19

"The meek also shall increase their joy in Jehovah, and the poor among men shall rejoice in the Holy One of Israel." — Isaiah 29:19 (ASV)

The meek also shall increase their joy in the Lord. —A new element enters into the ideal restoration of the future. Men had been weary of the name of the Holy One of Israel (Isaiah 30:11). In that better time it should be the source of joy and peace for the poor and the lowly, on whom Isaiah looked with all the yearnings of a prophet’s sympathy.
