Matthew Henry, Matthew Henry's Commentary on the Whole Bible… (1700s)
“ Note, Those that are of a fretful discontented spirit ought not to pore much, for, while they suffer their thoughts to dwell upon the causes of the calamity, the fire of their discontent is fed with fuel and burns the more furiously. Impatience is a sin that has its ill cause within ourselves, and that is musing, and its ill effects upon ourselves, and that is no less than burning. If therefore we would prevent the mischief of ungoverned passions, we must redress the grievance of ungoverned thoughts. ”
