The sixth aliyah gives the commandment of not moving a land boundary to fraudulently acquire land. Here also is a law of witnesses, where we are told that at least two witnesses are required for certain convictions. Also here is the law of a witness who testifies falsely: He shall have done to him what he intended to happen to the defendant. In this aliyah is the expression: an eye for an eye, a tooth for a tooth, which Rashi says, refers to monetary compensation for a physical injury.
Here are procedures for war. It says here that we are not to be afraid because G-d is with us. On the subject of war, verse 20:3 begins with the words Shma Yisroel. Rashi says this means that even if a person has only the merit of the mitzvah of saying the Shma alone, he still is worthy that G-d should deliver him from battle. Also here are exemptions from military service, such as someone betrothed but not yet married.
