The word testament has three usages or applications in the Bible:
2. Testament can refer to someone’s will, as in their last will and testament.
3. Lastly, the Bible is divided into two sections or testaments, so named because each encompasses a major covenant from God.
The first is the Old Testament, which refers to being made right with God by following a strict code of conduct and rules.
Although virtually all Bibles include the sections of Old Testament and New Testament, this usage is not actually found in the Bible’s text.
