10:2 A {a} wise man's heart [is] at his right hand; but a fool's heart [is] at his left.
(a) So that he does all things well and justly, where as the fool does the contrary.
10:2 Heart - His understanding is always present with him and ready to direct him. He mentions the right hand, because that is the common instrument of action. A fool's - His understanding is not effectual to govern his affections and actions.
10:1-3 Those especially who make a profession of religion, should keep from all appearances of evil. A wise man has great advantage over a fool, who is always at a loss when he has anything to do. Sin is the reproach of sinners, wherever they go, and shows their folly.
