Latex: text wrap in multirow in tables

In latex, if we have a very long text in multirow in tables need to be wraped
   \multicolumn{1}{|l|}{\multirow{2}{*}{ Very long text Very long text Very long text}}  &
 We can add {\parbox{7cm}} as below, where 7cm is the text length begin to wrap
   \multicolumn{1}{|l|}{\multirow{2}{*}{\parbox{7cm}{Very long text Very long text Very long text }}}  &

\begin{tabular}{ | b{2.6cm} | b{0.5cm}  | b{4.7cm}  | b{0.5cm}  | b{3cm}  | b{0.5cm} | b{4.7cm} |}
        \multicolumn{4}{l}{\ftext{Department Approval}} &
        \multicolumn{3}{l}{\ftext{Accepted by Appointee}} \\
