The OT is written in historical accounts that teach a theological truth. The written accounts are not exhaustive but rather are written to prove the teaching and application that is in the worship book. The worship book is the ot confession of the doctrines of grace in which we are guided in applying the doctrine. So you have all the historical accounts that are funneled into a specific confessional application in the Psalms. The Holy Spirits ministry in applying the holistic truth of salvation has limited our application of the ot accounts to the worship book.

In this sense the words that are used in these historical accounts are given their context in the teaching of the worship book. If you were to memorize the worship book you would be able to identify words and in these historical accounts phrases that come from the worship book. This is how the Holy Spirit draws us to the application in the teaching through the historical account.
Gods description of all the events in the OT are contained in His work in salvation. These events are written to show Gods work in redemption. He has made a covenant of redemption with His elect. We enter into a covenant that is contained. Every historical account is proving that He is the beginning and end in salvation. The saving of His people is given as a gift and the end of receiving that gift is Gods total victory over evil and the curse. So the health of His elect is contained in the teaching that is revealed and the effects of the full power of God that is mysterious that answer all of the concerns of His people in the rising and falling in the application of the teaching in the voices of His law which are blessing and cursing. Salvation is in God alone.
