In other words, Biblical law protects the marriage covenant by requiring the death penalty. Witnessed acts of adultery require punishment, by stoning, of both parties (Lev. 20:10, Deut. 22:22-24, John 8:7). Unwitnessed (but known) adultery could allow a husband to divorce his wife (Deut. 24:1, Matt. 1:19, Matt. 19:9).[1] This shows the seriousness with which God treats the marriage covenant. The family is the foundation of civilization. The marriage covenant is the foundation of the intact family. Thus God protects the marriage covenant by the ultimate civil penalty (if the adultery is witnessed) and the possibility of divorce (as a deterrent to unfaithfulness).
