❓What two Maxwell's equations are unified by the single four-dimensional tensor equation?

The single four-dimensional tensor equation $\partial_\mu F^{\mu\nu} = K^\nu$ unifies Gauss's Law ( $\nabla \cdot \mathbf{E} = \rho / \epsilon_0$ ) and the Ampère-Maxwell Law ( $\nabla \times \mathbf{B} = \mu_0 \mathbf{J} + \mu_0 \epsilon_0 \frac{\partial \mathbf{E}}{\partial t}$ ) into one compact relativistic expression.
