'Cutoff' in the Bible

For [if it were possible] I would wish that I myself were accursed, [separated, banished] from Christ for the sake [of the salvation] of my brothers, my natural kinsmen,

Then appreciate the gracious kindness and the severity of God: to those who fell [into spiritual ruin], severity, but to you, God’s gracious kindness—if you continue in His kindness [by faith and obedience to Him]; otherwise you too will be cut off.
