Charles Ellicott Commentary Psalms 95:10

"Forty years long was I grieved with [that] generation, And said, It is a people that do err in their heart, And they have not known my ways:" — Psalms 95:10 (ASV)

See Notes, Hebrews 3:17, New Testament Commentary.

I grieved. —Better, I loathed.

A people that do err. —Literally, a people of wanderers in heart. They are morally astray through ignorance of God’s paths.
