Using the effective Lagrangian approach, we study the decay behavior of the newly observed $B(5970)$ meson, which is assigned as the $2{}^3{S}_1$ state in the $B$ meson family. A more important prediction is the detailed information of the partial and total decay widths of $B(2{}^1{S}_0)$, $B_s(2{}^1{S}_0)$, and $B_s(2{}^3{S}_1)$ as the spin and strange partners of $B(5970)$, which can be tested in future experimental searches for these missing states.
