|Et non egent lúmine lucérnæ neque lúmine solis.||And they will not need the light of the lamp, nor of the sun.|
non egent = they will not need. From egeo, egere, to lack, to want, to need. This is future tense. The verb egere takes an ablative or a genitive, and so what they need is here found in the ablative case: lumine lucernae, the light of the lamp, and lumine solis, the light of the sun.
