'Thoughtlessness' in the Bible

acts of greed and covetousness, wickedness, deceit, unrestrained conduct, envy and jealousy, slander and profanity, arrogance and self-righteousness and foolishness (poor judgment).

but into the second [inner tabernacle, the Holy of Holies], only the high priest enters [and then only] once a year, and never without [bringing a sacrifice of] blood, which he offers [as a substitutionary atonement] for himself and for the sins of the people committed in ignorance.
