John 1:5

καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει, καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν.

And the light shines in the darkness, and the darkness did not overcome it


 * ἐν τῇ σκοτίᾳ - ἐν takes a dative σκοτίᾳ
 * φαίνει - shines, in the present tense. Some translate as keeps on shining, shines on etc. Good illustration of the imperfective aspect of the present tense.
 * οὐ - Greek is simpler than English in how to negate a verb
 * κατέλαβεν - aorist. Why aorist? It tried once, failed, and we are done?
