  We explore the recently observed $\Xi_b(6227)^{-}$ resonance to fix its
quantum numbers. To this end, we consider various possible scenarios: It can be
considered as either 1P/2S excitations of the $\Xi_b^-$ and $\Xi_b'(5935)^{-}$
ground state baryons with spin-$\frac{1}{2}$ or 1P/2S excitations of the ground
state $\Xi_b(5955)^{-}$ with spin-$\frac{3}{2}$. We calculate the masses of the
possible angular-orbital $1P$ and $2S$ excited states corresponding to each
channel employing the QCD sum rule technique. It is seen that all the obtained
masses are in agreement with the experimentally observed value, implying that
the mass calculations are not enough to distinguish the quantum numbers of the
state under question. Therefore, we extend the analysis to investigate the
possible decays of the same excited states into $\Lambda_b^0 K^-$ and
$\Xi_b^-\pi$. Using the light cone QCD sum rule method, we calculate the
corresponding strong coupling constants, which are used to extract the decay
widths of the modes under consideration. Our results on decay widths indicate
that the $\Xi_b(6227)^{-}$ is $1P$ angular-orbital excited state of the
$\Xi_b(5955)^{-}$ baryon with quantum numbers $J^P=\frac{3}{2}^{-}$.
