Charles Ellicott Commentary Ecclesiastes 10:2

"A wise man`s heart is at his right hand; but a fool`s heart at his left." — Ecclesiastes 10:2 (ASV)

At his right hand. —Perhaps better, towards his right hand, i.e., leads him to go to the right hand. The thought is the same as Ecclesiastes 2:13, namely, that though the actual results of wisdom are often disappointing, the superiority of wisdom over folly is undeniable.
