'Slips' in the Bible

as [for example] when a man goes into the forest with his neighbor to cut wood, and his hand swings the axe to cut down the tree, but the iron head slips off the wooden handle and hits his companion and he dies—the offender may escape to one of these cities and live;

For I pray, “May they not rejoice over me,Who, when my foot slips, would boast against me.”

Whoever attempts to restrain her [criticism] might as well try to stop the wind,And grasps oil with his right hand.

Because you [Judah] have forgotten the God of your salvationAnd have not remembered the Rock of your Stronghold—Therefore you plant lovely plantsAnd set the grounds with vine slips of a strange god,

Therefore, confess your sins to one another [your false steps, your offenses], and pray for one another, that you may be healed and restored. The heartfelt and persistent prayer of a righteous man (believer) can accomplish much [when put into action and made effective by God—it is dynamic and can have tremendous power].
