'Slips' in the Bible

{For example}, when somebody goes with his neighbor into the forest to cut wood, and the iron [head] slips from the handle [of the tool] and strikes his neighbor and he dies, [then] he may flee to one of these cities, and [so] he may live.

{Vengeance belongs to me} and [also] recompense, {for at the time their foot slips}, because the day of their disaster [is] near, {and fate comes quickly for them}.'
