Deuteronomy 19:6

Lest the avenger of the blood pursue the slayer, while his heart is hot, and overtake him, because the way is long, and slay him; whereas he [was] not worthy of death, inasmuch as he hated him not in time past.

Ver. 6. While his heart is hot.] As Nebuchadnezzar's oven - viz., with anger and grief, and such like passions; which, like heavy bodies down steep hills, once in motion move themselves, and know no ground but the bottom.
