Divine Blade

You touch a melee weapon, or a melee weapon wielded by a creature that is within reach. An aura glows around the weapon with a color that you choose, dimly lighting an area 5ft around the creature. Until the spell ends, the weapon deals an additional 1d4 radiant damage to any target it hits.

At Higher Levels. When you cast this spell using a spell slot of 2nd or higher, the damage increases by 1d4.
