Biblically, the death penalty could not be applied unless there were at least two eyewitnesses to the incident. Circumstantial evidence, even when strong, is not the equivalent of multiple eyewitnesses and therefore does not meet the Biblical standard. Interestingly, however, the Bible long ago acknowledged a specific eyewitness that only in recent decades has become recognized in Americans courts.
Recall the account of Cain's murder of his brother Abel from Genesis 4:8-10. When God asked Cain where his brother was and Cain lied, God specifically confronted him with the declaration: "The voice of your brother's blood is crying to Me from the ground" (v. 10). Blood cries out? Blood has a voice? How can that be? We now know that DNA has a voice - that it serves as an eyewitness to specific crimes, just as when it cried out to God about Abel's death. This voice therefore Biblically qualifies as one of the "two or three eyewitnesses" needed to secure the death penalty in a capital crime.
