Trespass Offering for Unknown Sins

Leviticus 5:17-19

Also if any sinne and doe against any of the commandements of the Lord, which ought not to be done, and knowe not and sinne and beare his iniquitie,

Then shall he bring a ramme without blemishe out of the flocke, in thy estimation worth two shekels for a trespasse offring vnto ye Priest: and the Priest shall make an atonement for him concerning his ignorance wherein he erred, and was not ware: so it shalbe forgiuen him.
