The influence of Chazal's moral tendencies and views on the shaping of Halacha

This question is relevant to many other laws, especially those taught in lectures. Specifically here, there is a general policy that is learned from "And they saved the congregation," and this reflects the general halachic approach regarding the laws of life. But it is clear to me that the Sages did not play games with the verses to reach the desired result. Otherwise, it is just a game and they essentially do whatever they want (or think). If there is a law that is based on a sabbath, they know how to say it, and are not ashamed. When a source is cited (unless it is a reference), then the source has meaning. The sabbath accompanies the sermon, or directs us what to teach. For example, in the verse "Thou shalt fear the Lord thy God," the "thou" comes to include something. The sabbath says that scholars of Torah multiply. There is a trigger in the text and the sabbath directs us what to do with it. Sometimes it is the other way around, the sabbath directs us to look for a textual trigger for the sermon.
