A word of caution. Language hides as well as reveals. But this can be misleading, for the word twb often has little to do with moral attributes. In legal contexts it can express either the notion of satisfaction or the notion of joy. The only way to determine this is by position and context.

The philological method is also concerned with parallel structures. Parallelism is an excellent way of establishing synonymity and equivalence. This is most clearly seen in the study of parallelism in biblical poetry, but suggestive examples can be found in parallel recensions within biblical narratives, as well as in parallel recensions of the midrash. An even more subtle use of parallelism may be adduced from the history of legal documents in the Near East. Each period uses its own particular linguistic concretization of the root metaphor.
