The meaning of a word is its use. Words can have dozens of uses. Their meaning is in a pattern. Word meaning is in a language-game. Patterns yield a motif.
Words describe or work in a form of life.
A big tapestry has many motifs. A Gospel pictures many forms of life. In an ancient tapestry there will be various motifs such as a king receiving homage, knights fighting, flags, a marriage, a banquet, gifts being given. Similarly in the first chapter of Mark various forms of life are depicted such as baptizing, disciples being enrolled, teaching, healing, and demons being cast out. If we are to understand a particular baptism form of life we need to learn the language games that the author takes for granted.
