More than one witness was required in criminal cases (Deuteronomy 17:6; 19:15). They were the first to execute the sentence on the condemned (Deuteronomy 13:9; 17:7; 1 Kings 21:13; Matthew 27:1; Acts 7:57, 58). False witnesses were liable to punishment (Deuteronomy 19:16-21). It was also an offence to refuse to bear witness (Leviticus 5:1).

Among people with whom writing is not common the evidence of a transaction is given by some tangible memorial or significant ceremony- Abraham gave seven ewe-lambs to Abimelech as an evidence of his property in the well of Beersheba. Jacob raised a heap of stones, "the heap of witness." as a boundary-mark between himself and Laban. (Genesis 21:30; 31:47,52) The tribes of Reuben and Gad raised an "altar" as a witness to the covenant between themselves and the rest of the nation. Joshua set up a stone as an evidence of the allegiance promised by Isr'l to God. (Joshua 22:10,26,34; 24:26,27) But written evidence was by no means unknown to the Jews. Divorce was to be proved by a written document. (24:1,3) In civil contracts, at least in later times documentary evidence was required and carefully preserved. (Isaiah 8:16; Jeremiah 32:10-16) On the whole the law was very careful to provide and enforce evidence for all its infractions and all transactions bearing on them. Among special provisions with respect to evidence are the following-

1. Two witnesses at least are required to establish any charge. (Numbers 35:30; 17:6; John 8:17; 2 Corinthians 13:1) comp. 1 Timothy 5:19
2. In the case of the suspected wife, evidence besides the husband's was desired. (Numbers 5:13)
3. The witness who withheld the truth was censured. (Leviticus 5:1)
4. False witness was punished with the penalty due to the offence which it sought to establish.
5. Slanderous reports and officious witness are discouraged. (Exodus 20:16; 23:1; Leviticus 18:16,18) etc.
6. The witnesses were the first executioners. (15:9; 17:7; Acts 7:58)
7. In case of an animal left in charge and torn by wild beasts, the keeper was to bring the carcass in proof of the fact and disproof of his own criminality. (Exodus 22:13)
8. According to Josephus, women and slaves were not admitted to bear testimony. In the New Testament the original notion of a witness is exhibited in the special form of one who attests his belief in the gospel by personal suffering. Hence it is that the use of the ecclesiastical term ("martyr." the Greek word for "witness," has arisen.
