To assist the matching of lattice field theory results to high energy continuum limit we evaluate Green's function where tensor quark bilinear operator is inserted at zero momentum in a 2-point for an arbitrary covariant gauge. This carried out both $\overline{\mathrm{MS}}$ and ${\mathrm{RI}}^{\ensuremath{'}}$ schemes four loops. The current anomalous dimension also calculated loops color group.
