Leviticus 5:1 mentions two ways in which someone would have information regarding a crime. In the first instance, someone would be an eyewitness (‘ēḏ) of the events. That is, they would have an experiential knowledge of what took place. In the second instance, someone would possess information about the crime through another person.
1 Lorsque quelqu'un, après avoir été mis sous serment comme témoin, péchera en ne déclarant pas ce qu'il a vu ou ce qu'il sait, il restera chargé de sa faute.
